%\section{Introduction}
%\label{sec:intro}
%
% The Association for Computing
% Machinery\footnote{\url{http://www.acm.org/}} is the world's largest
% educational and scientific computing society, which delivers
% resources that advance computing as a science and a
% profession. It was one of the
% early adopters of \TeX\ for its typesetting.
%
% It provided several different classes for a number of journals and
% conference proceedings. Unfortunately during the years since these
% classes were written, the code was patched many times, and
% supporting different versions of the classes became difficult.
%
% This package provides the uniform interface for all ACM
% publications. It is intended to replace all the different classes and
% packages and provide an up-to-date \LaTeX\ package.
%
% This package uses only free \TeX\ packages and fonts included in \TeX
% Live, Mik\TeX\ and other popular \TeX\ distributions. It is
% intended to be published in these distributions itself, which
% minimizes users' efforts in the installation and support of this
% package.
%
% I am grateful to
% Michael D.~Adams,
% Leif Andersen,
% Dirk Beyer,
% Benjamin Byholm,
% Michael Ekstrand,
% Matthew Fluet,
% Paolo G.~Giarrusso,
% Ben Greenman,

% The development version of the package is available at
% \url{https://github.com/borisveytsman/acmart}.
%
%\section{User's guide}
%\label{sec:ug}
%
%
% This class uses many commands and customizaton options, so it might
% appear intimidating for a casual user. Do not panic! Many of these
% commands and options can be safely left with their default values
% or the values recommended by your conference or journal editors. If
% you have problems or questions, do not hesitate to ask me directly
% or the community at \url{https://github.com/borisveytsman/acmart},
% \url{https://tex.stackexchange.com} or the closest \TeX\ Users
% Group. The world-wide \TeX\ Users Group is at
% \url{https://tug.org/}; please consider joining us if you use \TeX\
% regularly.
%
%\subsection{Installation}
%\label{sec:ug_install}
%
% Most probably, you already have this package installed in your
% favorite \TeX\ distribution; if not, you may want to upgrade. You
% may need to upgrade it anyway since this package uses a number of
% relatively recent packages, especially the ones related to fonts.
%
% The latest released version of this package can be found on CTAN:
% \url{https://www.ctan.org/pkg/acmart}. The development version can
% be found on GitHub: \url{https://github.com/borisveytsman/acmart}.
% At this address you can file a bug report---or even contribute your
% own enhancement by making a pull request.
%
% Please note that the version on Github is a development (or
% experimental) version: please download it for testing new features.
% The production version is the one on CTAN and ACM sites.
%
% Most users should not attempt to install this package themselves
% but should rather rely on their \TeX\ distributions to provide it. If you
% decide to install the package yourself, follow the standard rules:
% \begin{enumerate}
% \item Run |latex acmart.ins|. This will produce the file
% |acmart.cls|
% \item Put the files |acmart.cls| and |ACM-Reference-Format.bst|
% in places where \LaTeX{} can find them (see \cite{TeXFAQ} or
% the documentation for your \TeX{} system).\label{item:install}
% \item Update the database of file names. Again, see \cite{TeXFAQ}
% or the documentation for your \TeX{} system for the system-specific
% details.\label{item:update}
% \item The file |acmart.pdf| provides the documentation for the
% package. (This is probably the file you are reading now.)
% \end{enumerate}
% As an alternative to items~\ref{item:install} and~\ref{item:update}
% you can just put the files in the working directory where your
% |.tex| file is.
%
%
% This class uses a number of other packages. They are included in all
% major \TeX\ distributions (\TeX Live, Mac\TeX, Mik\TeX) of 2015 and
% later, so you probably have them installed. Just in case here is

%\subsection{Invocation and options}
%\label{sec:invocation}
%
% To use this class, put in the preamble of your document
% \begin{quote}
% \cs{documentclass}\oarg{options}|{acmart}|
% \end{quote}
% There are several options corresponding to the type of the document and
% its general appearance. They are described below. Generally
% speaking, the options have |key=value| forms, for example,
% \begin{verbatim}
% \documentclass[format=acmsmall, screen=true, review=false]{acmart}
% \end{verbatim}
%
%
% The option |format| describes the format of the output. There are
% several possible values for this option, for example,
% \begin{verbatim}
% \documentclass[format=acmtog]{acmart}
% \end{verbatim}
% Actually the words |format=| can be omitted, e.g.,
% \begin{verbatim}
% \documentclass[acmtog, review=false]{acmart}
% \end{verbatim}
% The possible formats are listed in
% Table~\ref{tab:opts_format}. Note that formats starting with |acm|
% are intended for journals and transactions, while formats starting
% with |sig| are intended for proceedings published as books.
%
% Note that sometimes conference proceedings are published as a
% special issue (or issues) of an ACM journal. In this case, you
% should use the journal format for a conference paper. Please
% contact your conference committee if in doubt.
%
% \begin{table}
% \centering
% \caption{The possible values for the \texttt{format} option}
% \label{tab:opts_format}
% \begin{tabularx}{\textwidth}{>{\ttfamily}lX}
% \toprule
% \normalfont Value & Meaning\\
% \midrule
% manuscript & A manuscript. This is the default. \\
% acmsmall & Small single-column format. Used for CIE, CSUR, DTRAP,
% JACM, JDIQ, JEA, JERIC,
% JETC, PACMHCI, PACMPL, TAAS, TACCESS, TACO, TALG, TALLIP (formerly TALIP), TCPS,
% TEAC, TECS, THRI, TIIS, TISSEC, TIST, TKDD, TMIS, TOCE, TOCHI, TOCL,
% TOCS, TOCT, TODAES, TODS, TOIS, TOIT, TOMACS, TOMM (formerly
% TOMCCAP), TOMPECS, TOMS, TOPC, TOPLAS, TOPS,
% TOS, TOSEM, TOSN, TRETS,
% TSAS, TSC, TSLP and TWEB, including special issues. \\
% acmlarge & Large single-column format. Used for
% IMWUT, JOCCH, POMACS and TAP, including special issues. \\
% acmtog & Large double-column format. Used for
% TOG, including annual conference Technical Papers.\\
% sigconf & Proceedings format for most ACM
% conferences (with the exceptions listed below) and all ICPS
% volumes.\\
% sigplan & Proceedings format for SIGPLAN conferences.\\
% sigchi & Proceedings format for SIGCHI conferences.\\
% sigchi-a & Format for SIGCHI extended abstracts.\\
% \bottomrule
% \end{tabularx}
% \end{table}
%
% There are several Boolean options that can take |true| or |false|
% values. They are listed in Table~\ref{tab:opts_bool}. The words
% |=true| can be omitted when setting a Boolean option, so instead of
% |screen=true| one can write just |screen|, for example,
% \begin{verbatim}
% \documentclass[acmsmall, screen, review]{acmart}
% \end{verbatim}
% The option |review| is useful when combined with the |manuscript| format
% option. It provides a version suitable for reviewers and
% copy editors.
%
% The default for the option |screen| depends on the publication. At
% present it is |false| for all publications \emph{but} PACM, since
% PACM is now electronic-only. Thus PACM titles~(see
% Table~\ref{tab:pubs}) set this option to |true|. In the future this
% option may involve additional features suitable for on-screen
% versions of articles.
%
% The option |natbib| is used when the corresponding
% \BibTeX\ style is based on |natbib|. In most cases you do not need
% to set it. See
% Section~\ref{sec:ug_bibliography}.
%
% The option |anonymous| is used
% for anonymous review processes and causes all author information to be
% obscured.
%
% The option |timestamp| is used to include a time stamp in the
% footer of each page. When preparing a document, this can help avoid
% confusing different revisions. The footer also includes the page range of
% the document. This helps detect missing pages in hard copies.
%
% The option |authordraft| is intended for author's drafts that are not
% intended for distribution. It typesets a copyright block to give the
% author an idea of its size and the overall size of the paper but
% overprints it with the phrase ``Unpublished working draft. Not for
% distribution.'', which is also used as a watermark. This option sets
% |timestamp| and |review| to |true|, but these can be
% overriden by setting these options to |false| \emph{after}
% setting |authordraft| to |true|.
%
% \begin{table}
% \centering
% \caption{Boolean options}
% \label{tab:opts_bool}
% \begin{tabularx}{\textwidth}{>{\ttfamily}l>{\ttfamily}lX}
% \toprule
% \normalfont Option & \normalfont Default & Meaning\\
% \midrule
% review & false & A review version: lines are numbered and
% hyperlinks are colored\\
% screen & {\rmfamily see text} & A screen version:
% hyperlinks are colored\\
% natbib & true & Whether to use the |natbib| package (see
% Section~\ref{sec:ug_bibliography})\\
% anonymous & false & Whether to make author(s) anonymous\\
% authorversion & false & Whether to generate a special
% version for the authors' personal use or posting (see
% Section~\ref{sec:ug_topmatter})\\
% timestamp & false & Whether to put a time stamp in the
% footer of each page\\
% authordraft & false & Whether author's-draft mode is enabled\\
% acmthm & true & Whether to define theorem-like environments, see
% Section~\ref{sec:ug_theorems}\\
% \bottomrule
% \end{tabularx}
% \end{table}
%
%
%
%\subsection{Top matter}
%\label{sec:ug_topmatter}
%
% A number of commands set up \emph{top matter} or (in
% computer science jargon) \emph{metadata} for an article. They
% establish the publication name, article title, authors, DOI and
% other data. Some of these commands, like \cs{title} and \cs{author},
% should be put by the authors. Others, like \cs{acmVolume} and
% \cs{acmDOI}---by the editors. Below we describe these commands and
% mention who should issue them. These macros should be used
% \emph{before} the \cs{maketitle} command. Note that in previous
% versions of ACM classes some of these commands should be used before
% \cs{maketitle}, and some after it. Now they all must be used before
% \cs{maketitle}.
%
%
% This class internally loads the |amsart| class, so many top-matter
% commands are inherited from |amsart|~\cite{Downes04:amsart}.
%
% \DescribeMacro{\acmJournal}%
% The macro \cs{acmJournal}\marg{shortName} sets the name of the
% journal or transaction for journals and transactions. The argument
% is the short name of the publication \emph{in uppercase}, for
% example,
% \begin{verbatim}
% \acmJournal{TOMS}
% \end{verbatim}
% The currently recognized journals are listed in
% Table~\ref{tab:pubs}. Note that conference proceedings published in
% \emph{book} form do not set this macro.

% \bottomrule
% \end{tabularx}
% \end{table}
%
% It is expected that this command is inserted by the author of the
% manuscript when she decides to which journal to submit the
% manuscript.
%
% \DescribeMacro{\acmConference}%
% The macro
% \cs{acmConference}\oarg{short name}\marg{name}\marg{date}\marg{venue} is
% used for conference proceedings published in the book form. The
% arguments are the following:
% \begin{description}
% \item[short name:] the abbreviated name of the conference (optional).
% \item[name:] the name of the conference.
% \item[date:] the date(s) of the conference.
% \item[venue:] the place of the conference.
% \end{description}
% Examples:
% \begin{verbatim}
% \acmConference[TD'15]{Technical Data Conference}{November
% 12--16}{Dallas, TX, USA}
% \acmConference{SA'15 Art Papers}{November 02--06, 2015}{Kobe, Japan}
% \end{verbatim}
%
% \DescribeMacro{\acmBooktitle}%
% By default we assume that conference proceedings are published
% in the book named \emph{Proceedings of \textsc{CONFERENCE}}, where
% \textsc{CONFERENCE} is the name of the conference inferred from the
% command \cs{acmConference} above. However, sometimes the book title
% is different. The command \cs{acmBooktitle} can be used to set this
% title, for example,
% \begin{verbatim}
% \acmBooktitle{Companion to the first International Conference on the
% Art, Science and Engineering of Programming (Programming '17)}
% \end{verbatim}
%
% \DescribeMacro{\editor}%
% In most cases, conference proceedings are edited. You can use the
% command \cs{editor}\marg{editor} to set the editor of the volume.
% This command can be repeated, for example,
% \begin{verbatim}
% \editor{Jennifer B. Sartor}
% \editor{Theo D'Hondt}
% \editor{Wolfgang De Meuter}
% \end{verbatim}
%
%
% \DescribeMacro{\title}%
% The command |\title|, as in the |amsart| class, has two arguments: one
% optional, and one mandatory:
% \begin{flushleft}
% |\title[|\meta{ShortTitle}|]{|\meta{FullTitle}|}|
% \end{flushleft}
% The mandatory argument is the full title of the article. The
% optional argument, if present, defines the shorter version of the
% title for running heads. If the optional argument is absent, the
% full title is used instead.
%
% It is expected that this command is inserted by the author of the
% manuscript.
%
% \DescribeMacro{\subtitle}%
% Besides title, ACM classes allow a subtitle, set with the
% \cs{subtitle}\marg{subtitle} macro.
%
% The commands for specifying authors are highly structured.
% The reason is they serve double duty: the authors' information is
% typeset in the manuscript \emph{and} is used by the metadata
% extraction tools for indexing and cataloguing. Therefore it is very
% important to follow the guidelines exactly.
%
% \DescribeMacro{\author}%
% \DescribeMacro{\orcid}
% \DescribeMacro{\affiliation}%
% \DescribeMacro{\email}%
% The basic commands are \cs{author}, \cs{orcid} (for the researchers
% registered with ORCID, \url{http://www.orcid.org/}), \cs{affiliation} and
% \cs{email}. In the simplest case, you enter them in this order:
% \begin{verbatim}
% \author{...}
% \orcid{...}
% \affiliation{...}
% \email{...}
% \end{verbatim}
% Do \emph{not} use the \LaTeX\ \cs{and} macro! Each author deserves
% his or her own \cs{author} command.
%
% Note that some formats do not typset e-mails or ORCID identifiers.
% Do not worry: the metadata tools will get them.
%
% Sometimes an author has several affiliations. In this case, the
% \cs{affiliation} command should be repeated:
% \begin{verbatim}
% \author{...}
% \orcid{...}
% \affiliation{...}
% \affiliation{...}
% \email{...}
% \end{verbatim}
% Similarly you can repeat the \cs{email} command.
%
% You may have several authors with the same affiliation, different
% affiliations, or overlapping affiliations (author~$A_1$ is affiliated
% with institutions $I_1$ and $I_2$, while author $A_2$ is affiliated
% with $I_2$ only, author $A_3$ is affiliated with
% $I_1$ and $I_3$, etc.). The recommended solution is to put the
% \cs{affiliation} commands after each author, possibly repeating them:
% \begin{verbatim}
% \author{...}
% \orcid{...}
% \affiliation{...}
% \affiliation{...}
% \email{...}
% \author{...}
% \orcid{...}
% \affiliation{...}
% \email{...}
% \author{...}
% \orcid{...}
% \affiliation{...}
% \affiliation{...}
% \email{...}
% \end{verbatim}
% In some cases, when several authors share the same affiliation, you can
% try to save space using the format
% \begin{verbatim}
% \author{...}
% \email{...}
% \author{...}
% \email{...}
% \affiliation{...}
% \end{verbatim}
% However, this format is not generally recommended.
%
% \DescribeMacro{\additionalaffiliation}%
% In some cases, too many affiliations can take too much space. The
% command \cs{additionalaffiliation}\marg{affiliation} creates a
% footnote after an author's name with the words ``Also with
% \marg{affiliation}''. You should use this command only as a last
% resort. An example of usage is:
% \begin{verbatim}
% \author{G. Tobin}
% \author{Ben Trovato}
% \additionalaffiliation{%
% \institution{The Th{\o}rv{\"a}ld Group}
% \streetaddress{1 Th{\o}rv{\"a}ld Circle}
% \city{Hekla}
% \country{Iceland}}
% \affiliation{%
% \institution{Institute for Clarity in Documentation}
% \streetaddress{P.O. Box 1212}
% \city{Dublin}
% \state{Ohio}
% \postcode{43017-6221}}
% \end{verbatim}

% The \cs{affiliation} and \cs{additionalaffiliation} commands are
% further structured to interact with the metadata extraction tools.
% Inside these commands you should use the \cs{position},
% \cs{institution}, \cs{department}, \cs{city}, \cs{streetaddress},
% \cs{state}, \cs{postcode} and \cs{country} macros to indicate the
% corresponding parts of the affiliation. Note that in some cases
% (for example, journals) these parts are not printed in the resulting
% copy, but they \emph{are} necessary since they are used by the XML
% metadata extraction programs. Do \emph{not} put commas or |\\|
% between the elements of \cs{affiliation}. They will be provided
% automatically.
%
%
% An example of the author block:
% \begin{verbatim}
% \author{A. U. Thor}
% \orcid{1234-4564-1234-4565}
% \affiliation{%
% \institution{University of New South Wales}
% \department{School of Biomedical Engineering}
% \streetaddress{Samuels Building (F25), Kensington Campus}
% \city{Sidney}
% \state{NSW}
% \postcode{2052}

% \email{author@nsw.au.edu}
% \author{A. N. Other}
% \affiliation{%
% \institution{University of New South Wales}
% \city{Sidney}
% \state{NSW}
% \country{Australia}}
% \author{C. O. Respondent}
% \orcid{1234-4565-4564-1234}
% \affiliation{%
% \institution{University of Pennsylvania}
% \city{Philadelphia}
% \state{PA}
% \country{USA}}
% \affiliation{%
% \institution{University of New South Wales}
% \city{Sidney}
% \state{NSW}
% \country{Australia}}
% \end{verbatim}
%
% Note that the old ACM conference formats did not allow more than six
% authors and required some effort from authors to achieve
% alignment. The new format is much better in this.
%
% Sometimes an author works in several departments within the same
% insitution. There could be two situations: the departments are
% independent, or one department is within another. In the first
% case, just repeat the command \cs{department} several times. To
% handle the second case the command has an optional numerical
% parameter. The departments with higher numbers are higher in the
% organizational chart. Compare
% \begin{verbatim}
% \affiliation{%
% \department[0]{Department of Lunar Studies} % 0 is the default
% \department[1]{John Doe Institute} % higher than 0
% \institution{University of San Serriffe}
% \country{San Serriffe}}
% \end{verbatim}
% and
% \begin{verbatim}
% \affiliation{%
% \department{Department of Lunar Studies} % Not in the John Doe Institute!
% \department{John Doe Institute}
% \institution{University of San Serriffe}
% \country{San Serriffe}}
% \end{verbatim}
%
%
% The command \cs{affiliation} formats its output according to
% American conventions. This might be wrong for some cases.
% Consider, for example, a German address. In Germany, the postcode is
% put before the city and is not separated by a comma. We can handle this
% order using
% \begin{verbatim}
% \affiliation{%
% \institution{Fluginstitut}
% \streetaddress{Sonnenallee 17}
% \postcode{123456}
% \city{Helm}
% \country{Germany}}
% \end{verbatim}
% However, the comma after the postcode is unfortunate: the address will
% be typeset (in some formats) as
% \begin{verbatim}
% Fluginstitut
% Sonenallee 17
% 123456, Helm, Germany
% \end{verbatim}
%
%
% To overcome this problem, the command \cs{affiliation} has an
% optional parameter |obeypunctuation|, which can be |false| (the
% default) or |true|. If this parameter is |true|, \cs{afffiliation}
% obeys the author's command. Thus
% \begin{verbatim}
% \affiliation[obeypunctuation=true]{%
% \institution{Fluginstitut}\\
% \streetaddress{Sonnenallee 17}\\
% \postcode{123456}
% \city{Helm},
% \country{Germany}}
% \end{verbatim}
% will be typeset as
% \begin{verbatim}
% Fluginstitut
% Sonenallee 17
% 123456 Helm, Germany
% \end{verbatim}
%
% Note that you should \emph{not} use this option for journals.
%
% It is expected that these commands are inserted by the author of the
% manuscript.
%
% \DescribeMacro{\thanks}%
% Like |amsart| (and unlike standard \LaTeX{}), we allow
% |\thanks| only \emph{outside} of the commands |\title| and |\author|.
% This command is obsolete and should \emph{not} be used in most
% cases. Do not list your acknowledgments or grant sponsors here.
% Put this information in the |acks| environment (see
% Section~\ref{sec:ug_acks}).
%
% \DescribeMacro{\authorsaddresses}%
% In some formats, addresses are printed as a footnote on the first
% page. By default \LaTeX\ typesets them itself using the information
% you give it. However, you can override its choice using the
% commmand \cs{authorsaddresses}\marg{contact addresses}, for example,
% \begin{verbatim}
% \authorsaddresses{%
% Authors' addresses: G.~Zhou, Computer Science Department, College of
% William and Mary, 104 Jameson Rd, Williamsburg, PA 23185, US;
% V.~B\'eranger, Inria Paris-Rocquencourt, Rocquencourt, France;
% A.~Patel, Rajiv Gandhi University, Rono-Hills, Doimukh, Arunachal
% Pradesh, India; H.~Chan, Tsinghua University, 30 Shuangqing Rd,
% Haidian Qu, Beijing Shi, China; T.~Yan, Eaton Innovation Center,
% Prague, Czech Republic; T.~He, C.~Huang, J.~A.~Stankovic University
% of Virginia, School of Engineering Charlottesville, VA 22903, USA;
% T. F. Abdelzaher, (Current address) NASA Ames Research Center,
% Moffett Field, California 94035.}
% \end{verbatim}
% You can \emph{suppress} printing authors' addresses by setting them
% to an empty string: |\authorsaddresses{}|.
%
% \DescribeMacro{\titlenote}%
% \DescribeMacro{\subtitlenote}%
% \DescribeMacro{\authornote}%
% While the command \cs{thanks} generates a note without a footnote
% mark, sometimes the authors might need notes more tightly connected
% to the title, subtitle or author. The commands \cs{titlenote},
% \cs{subtitlenote} and \cs{authornote} that follow the corresponding
% commands (\cs{title}, \cs{subtitle} and \cs{author}) generate such
% notes. For example,
% \begin{verbatim}
% \title{This is a title}
% \titlenote{This is a titlenote}
% \author{A. U. Thor}
% \authornote{This is an authornote}
% \end{verbatim}
%
% Please never use a \cs{footnote} inside an \cs{author} or \cs{title}
% command since this confuses the metadata extraction software. (Actually
% these commands now produce errors.)
%
% \DescribeMacro{\authornotemark}%
% Sometimes one may need to have the same footnote connected to
% several authors. The command \cs{authornotemark}\oarg{number} adds
% just the footnote mark, for example,
% \begin{verbatim}
% \author{A. U. Thor}
% \authornote{Both authors contributed equally to the paper}
% ...
% \author{A. N. Other}
% \authornotemark[1]
% \end{verbatim}
% The correct numbering of these marks is the responsibility of the
% user.
%
% \DescribeMacro{\acmVolume}%
% \DescribeMacro{\acmNumber}%
% \DescribeMacro{\acmArticle}%
% \DescribeMacro{\acmYear}%
% \DescribeMacro{\acmMonth}%
% The macros \cs{acmVolume}, \cs{acmNumber}, \cs{acmArticle},
% \cs{acmYear} and \cs{acmMonth} are inserted by the editor and set
% the journal volume, issue, article number, year and month
% corrspondingly. The arguments of all these commands, including
% \cs{acmMonth}, is numerical. For example,
% \begin{verbatim}
% \acmVolume{9}
% \acmNumber{4}
% \acmArticle{39}
% \acmYear{2010}
% \acmMonth{3}
% \end{verbatim}
% Note that \cs{acmArticle} is used not only for journals but also
% for some conference proceedings.
%
% \DescribeMacro{\acmArticleSeq}%
% The articles in the same issue of a journal have a \emph{sequence
% number}. It is used to vertically position the black blob on the first
% page of some formats. By default it is the same as the article number,
% but the command \cs{acmArticleSeq}\marg{n} can be used to change it:
% \begin{verbatim}
% \acmArticle{39} % The sequence number will be 39 by default
% \acmArticleSeq{5} % We redefine it to 5
% \end{verbatim}
% Setting this number to zero suppresses the blob.
%
% \DescribeMacro{\acmSubmissionID}%
% If your paper got a Submission~ID from the Conference Management
% System, put it here:
% \begin{verbatim}
% \acmSubmissionID{123-A56-BU3}
% \end{verbatim}
%
%
% \DescribeMacro{\acmPrice}%
% The macro \cs{acmPrice}\marg{price} sets the price for the article,
% for example,
% \begin{verbatim}
% \acmPrice{25.00}
% \end{verbatim}
% Note that you do not need to put the dollar sign here, just the
% amount. By default the price is \$15.00, unless the copyright is
% set to |usgov| or |rightsretained|, when it is suppressed. Note that to
% override the defaults you need to set the price \emph{after} the
% \cs{setcopyright} command. Also, the
% command |\acmPrice{}| suppresses the printing of the price.
%
% \DescribeMacro{\acmISBN}%
% Book-like volumes have ISBN numbers attached to them. The macro
% \cs{acmISBN}\marg{ISBN} sets it. Normally it is set by the
% typesetter, for example,
% \begin{verbatim}
% \acmISBN{978-1-4503-3916-2}
% \end{verbatim}
% Setting it to the empty string, as |\acmISBN{}|, suppresses printing the
% ISBN.
%
% \DescribeMacro{\acmDOI}%
% The macro \cs{acmDOI}\marg{DOI} sets the DOI of the article, for
% example,
% \begin{verbatim}
% \acmDOI{10.1145/9999997.9999999}
% \end{verbatim}
% It is normally set by the typesetter. Setting it to the empty
% string, as |\acmDOI{}|, suppresses the DOI.
%
%
% \DescribeMacro{\acmBadgeR}%
% \DescribeMacro{\acmBadgeL}%
% Some conference articles get special distinctions, for example, the
% artifact evaluation for PPoPP~2016
% (see~\url{http://ctuning.org/ae/ppopp2016.html}). These articles
% display special badges supplied by the conference organizers. This
% class provides commands to add these badges:
% \cs{acmBadgeR}\oarg{url}\marg{graphics} and
% \cs{acmBadgeL}\oarg{url}\marg{graphics}. The first command puts the
% badge to the right of the title, and the second one---to the left.
% The exception is the |sigchi-a| mode for SIGCHI extended abstracts,
% which puts the badges on the left margin. The arguments have the
% following meaning: \oarg{url}, if provided, sets the link to the
% badge authority in the screen version, while \marg{graphics} sets
% the graphics file with the badge image. The file must be a cropped
% square, which is scaled to a standard size in the output. For
% example, if the badge image is |ae-logo.pdf|, the command is
% \begin{verbatim}
% \acmBadgeR[http://ctuning.org/ae/ppopp2016.html]{ae-logo}
% \end{verbatim}
%
%
%
% \DescribeMacro{\startPage}%
% The macro \cs{startPage}\marg{page} sets the first page of the
% article in a journal or book. It is used by the typesetter.
%
%
% \DescribeMacro{\terms}%
% \DescribeMacro{\keywords}%
% The command
% \cs{keywords}\marg{keyword, keyword,\ldots} sets keywords for the
% article. They must be
% separated by commas, for example,
% \begin{verbatim}
% \keywords{wireless sensor networks, media access control,
% multi-channel, radio interference, time synchronization}
% \end{verbatim}
%
% \DescribeEnv{CCSXML}%
% \DescribeMacro{\ccsdesc}%
% ACM publications are classified according to the ACM Computing
% Classification Scheme (CCS). CCS codes are used both in the typeset
% version of the publications \emph{and} in the metadata in various
% databases. Therefore you need to provide both \TeX\ commands and XML
% metadata with the paper.
%
% The tool at \url{http://dl.acm.org/ccs.cfm} can be used to generate
% CCS codes. After you select the topics, click on ``Generate CCS

%
% \DescribeMacro{\setcopyright}
% There are several possibilities for the copyright of the papers
% published by the ACM: the authors may transfer the rights to the ACM,
% license them to the ACM, some or all authors might be employees of the
% US or Canadian governments, etc. Accordingly the command
% \verb|\setcopyright{...}| is introduced. Its argument is the
% copyright status of the paper, for example,
% \verb|\setcopyright{acmcopyright}|. The possible values for this
% command are listed in Table~\ref{tab:setcopyright}.
%
% \begin{table}
% \centering

% \bottomrule
% \end{tabularx}
% \end{table}
% The ACM submission software should generate the right command for you
% to paste into your file.
%
%
% \DescribeMacro{\copyrightyear}%
% Each copyright statement must have the year of copyright. By
% default it is the same as \cs{acmYear}, but you can override this
% using the macro \cs{copyrightyear}, e.g.,
% \begin{verbatim}
% \acmYear{2016}
% \copyrightyear{2015}
% \end{verbatim}
%
% There is a special case for a personal copy that the authors may be
% allowed to generate for their use or a posting on a personal site
% (check the instructions for the specific journal or conference for
% the details). The document option |authorversion=true| produces a
% special form of the copyright statement for this case. Note that
% you still need the \cs{setcopyright} command and (optionally)
% \cs{copyrightyear} command to tell \TeX\ about the copyright owner and
% year. Also, you should be aware that due to the different sizes of
% the permssion blocks for the printed version and authors' version,
% the page breaks might be different between them.
%
% \DescribeEnv{abstract}%
% The environment |abstract| must \emph{precede} the \cs{maketitle}
% command. Again, this is different from the standard \LaTeX.
%
%
% \DescribeEnv{teaserfigure}%
% A special kind of figure is used for many two-column conference
% proceedings. This figure is placed just after the authors but
% before the main text. The environment |teaserfigure| is used for these
% figures. This environment must be used \emph{before}
% \cs{maketitle}, for example,
% \begin{verbatim}
% \begin{teaserfigure}
% \includegraphics[width=\textwidth]{sampleteaser}
% \caption{This is a teaser}
% \label{fig:teaser}
% \end{teaserfigure}
% \end{verbatim}
%
%
% \DescribeMacro{\settopmatter}%
% Some information in the top matter is printed for certain journals
% or proceedings and suppressed for others. You can override these
% defaults using the command \cs{settopmatter}\marg{settings}. The
% settings and their meanings are listed in
% Table~\ref{tab:settopmatter}. For example,
% \begin{verbatim}
% \settopmatter{printacmref=false, printccs=true, printfolios=true}
% \end{verbatim}
% The parameter |authorsperrow| requires some explanation. In
% conference proceedings authors' information is typeset in boxes,
% several boxes per row (see |sample-sigconf.pdf|,
% |sample-sigplan.pdf|, etc.). The number of boxes per row is
% determined automatically. If you want to override this,
% you can do it using this parameter, for example,
% \begin{verbatim}
% \settopmatter{authorsperrow=4}
% \end{verbatim}
% However, in most cases you should \emph{not} do this and should use the
% default settings. Setting |authorsperrow| to $0$ will revert it to the
% default settings.
%
% \begin{table}

% \end{table}
%
%
% \DescribeMacro{\received}%
% The command \cs{received}\oarg{stage}\marg{date} sets the history of
% the publication. The~\oarg{stage} argument is optional; the default
% is |Received| for the first date and |revised| for the subsequent
% ones. For example,
% \begin{verbatim}
% \received{February 2007}
% \received[revised]{March 2009}
% \received[accepted]{June 2009}
% \end{verbatim}
%
%
% \DescribeMacro{\maketitle}%
% The macro \cs{maketitle} must be the last command in the top-matter
% group. That is it must follow the commands defined in this section.
%
%
% \DescribeMacro{\shortauthors}%
% \emph{After} the command \cs{maketitle}, the macro \cs{shortauthors}
% stores the names of the authors for the running head. You can
% redefine it if the list of author's name is too long, e.g.,
% \begin{verbatim}
% \maketitle
% \renewcommand{\shortauthors}{Zhou et al.}

%
%\subsection{Algorithms}
%\label{sec:ug_algorithms}
%
% There are now several good packages for typesetting
% algorithms~\cite{Fiorio15, Brito09, Heinz15}, and the authors are
% free to choose their favorite one.
%
%
%
%\subsection{Figures and tables}
%\label{sec:ug_floats}
%
% The new ACM styles use the standard \LaTeX\ interface for figures and
% tables. There are some important items to be aware of, however.
%
% \begin{enumerate}
% \item The captions for figures must be entered \emph{after} the
% figure bodies and for tables \emph{before} the table bodies.
% \item The ACM uses the standard types for figures and tables and adds
% several new ones. In total there are the following types:
% \begin{description}
% \item[figure, table:] a standard figure or table taking a full text
% width in one-column formats and one column width in two-column formats.
% \item[figure*, table*] in two-column formats, a special figure or
% table taking a full text width.
% \item[teaserfigure:] a special figure before \cs{maketitle}.
% \item[sidebar, marginfigure, margintable:] in the |sigchi-a| format,
% special sidebars, tables and figures in the margin.
% \end{description}
%
% \item Accordingly, when scaling images, one should use the
% following sizes:
% \begin{enumerate}
% \item For |teaserfigure|, |figure| in one-column mode or |figure*| in
% two-column mode, use \cs{textwidth}. In one-column mode, you can also
% use \cs{columnwidth}, which coincides with \cs{textwidth} in this
% case.
% \item For |figure| in two-column mode, use \cs{columnwidth}.
% \item For |marginfigure|, use \cs{marginparwidth}.
% \item For |figure*| in SIGCHI extended
% abstracts, use \cs{fulltextwidth}.
% \end{enumerate}
%
% \end{enumerate}
%
% It is strongly recommended to use the package |booktabs|~\cite{Fear05}
% and follow its main principles of typography with respect to tables:
% \begin{enumerate}
% \item Never, ever use vertical rules.
% \item Never use double rules.
% \end{enumerate}
% It is also a good idea not to overuse horizontal rules.
%
% For table \emph{footnotes} you have several options described in the TeX
% FAQ~\cite{TeXFAQ}. The simplest one is to use a \cs{minipage}
% environment:
% \begin{verbatim}
% \begin{table}
% \caption{Simulation Configuration}
% \label{tab:conf}
% \begin{minipage}{\columnwidth}
% \begin{center}
% \begin{tabular}{ll}
% \toprule
% TERRAIN\footnote{This is a table footnote. This is a
% table footnote. This is a table footnote.} &
% (200\,m$\times$200\,m) Square\\
% Node Number & 289\\
% Node Placement & Uniform\\
% Application & Many-to-Many/Gossip CBR Streams\\
% Payload Size & 32 bytes\\
% Routing Layer & GF\\
% MAC Layer & CSMA/MMSN\\
% Radio Layer & RADIO-ACCNOISE\\
% Radio Bandwidth & 250Kbps\\
% Radio Range & 20m--45m\\
% \bottomrule
% \end{tabular}
% \end{center}
% \bigskip
% \footnotesize\emph{Source:} This is a table
% sourcenote. This is a table sourcenote. This is a table
% sourcenote.
%
% \emph{Note:} This is a table footnote.
% \end{minipage}
% \end{table}
% \end{verbatim}
%
% \DescribeEnv{sidebar}%
% \DescribeEnv{marginfigure}%
% \DescribeEnv{margintable}%
% SIGCHI extended abstracts use margin space extensively. This package
% provides three environments for this with optional captions:
% \begin{description}
% \item[sidebar:] textual information in the margin
% \item[marginfigure:] a figure in the margin
% \item[margintable:] a table in the margin
% \end{description}
%
%
% Tables and figures (including margin tables and margin figures) are
% by default centered. However, in some cases (for example, when you
% use several subimages per figure) you may need to override this.
% A good way to do so is to put the contents into a
% \cs{minipage} of the width \cs{columnwidth}.
%
%\subsection{Theorems}
%\label{sec:ug_theorems}
%
% The ACM classes define two theorem styles and several pre-defined
% theorem environments:
% \begin{description}
% \item[acmplain:] this is the style used for
% |theorem|,
% |conjecture|,
% |proposition|,
% |lemma| and
% |corollary|, and
% \item[acmdefinition:] this is the style used for
% |example| and
% |definition|.
% \end{description}
%
%
% These environments are defined by default. In the unusual
% circumstance that a user does not wish to have these environments
% defined, the option |acmthm=false| in the preamble will suppress
% them.
%
%\subsection{Online-only and offline-only material}
%\label{sec:ug_screen}
%
% \DescribeEnv{printonly}%
% \DescribeEnv{screenonly}%
% Some supplementary material in ACM publications is put online but
% not in the printed version. The text inside the environment
% |screenonly| will be typeset only when the option |screen| (see
% Section~\ref{sec:invocation}) is set to |true|. Conversely, the
% text inside the environment |printonly| is typset only when this
% option is set to |false|. For example,
% \begin{verbatim}
% \section{Supplementary materials}
%
% \begin{printonly}
% Supplementary materials are available in the online version of this paper.
% \end{printonly}
%
% \begin{screenonly}
% (The actual supplementary materials.)
% \end{screenonly}
% \end{verbatim}
%
% We use the |comment| package for typesetting this code, so
% |\begin| and |\end| should start on a line of their own with
% no leading or trailing spaces.
%
%\subsection{Note about anonymous mode}
%\label{sec:ug_anonymous}
%
% \DescribeEnv{anonsuppress}%
% When the option |anonymous| is selected, \TeX\ suppresses author
% information (including the number of authors) for a blind review.
% However, sometimes the information identifying the authors may be
% present in the body of the paper. For example,
% \begin{verbatim}
% \begin{anonsuppress}
% This is the continuation of the previous work by the author
% \cite{prev1, prev2}.
% \end{anonsuppress}
% \end{verbatim}
%
% As for the |printonly| and |screenonly| environments,
% |\begin{anonsuppress}| and |\end{anonsuppress}| should start on a
% line of their own with no leading or trailing spaces.
%
%\subsection{Acknowledgments}
%\label{sec:ug_acks}
%
% The traditional ``Acknowledgments'' section is conventionally used
% to thank persons and granting agencies for their help and support.
% However, there are several important considerations about this
% section.
%
% First, in anonymous mode this section must be omitted: it gives
% too much information to reviewers. Second, data about
% grants is extracted and stored separately by the postprocessing
% software. ACM classes provide facilities for both these tasks.
%
% \DescribeEnv{acks}%
% The environment |acks| starts an unnumbered section
% ``Acknowledgments'' unless the anonymous mode is chosen. Put all
% thanks inside this environment.
%
% As for the |printonly| and |screenonly| environments,
% |\begin{acks}| and |\end{acks}| should start on a
% line of their own with no leading or trailing spaces.
%
% \DescribeMacro{\grantsponsor}%
% \DescribeMacro{\grantnum}%
% All financial support \emph{must} be listed using the commands
% \cs{grantsponsor} and \cs{grantnum}. These commands tell the
% postprocessing software about the granting organization and
% grant. The format of these commands is the following:
% \begin{quote}
% \cs{grantsponsor}\marg{sponsorID}\marg{name}\marg{url}\\
% \cs{grantnum}\oarg{url}\marg{sponsorID}\marg{number}.
% \end{quote}
% Here \marg{sponsorID} is the unique ID used to match grants to
% sponsors, \marg{name} is the name of the sponsor, \marg{url} is its
% URL, and \marg{number} is the grant number. The \marg{sponsorID} of
% the \cs{grantnum} command must correspond to the \marg{sponsorID} of a
% \cs{grantsponsor} command. Some awards have their own web pages,
% which you can include using the optional argument of the \cs{grantnum}
% command.
%
% At present \marg{sponsorID} is chosen by the authors and can be an
% arbitrary key in the same way the label of a \cs{cite} is arbitrarily
% chosen. There might be a change to this policy if the ACM decides to
% create a global database of sponsoring organizations.
%
% Example:
% \begin{verbatim}
% \begin{acks}
% The authors would like to thank Dr. Yuhua Li for providing the
% matlab code of the \textit{BEPS} method.
%
% The authors would also like to thank the anonymous referees for
% their valuable comments and helpful suggestions. This work is
% supported by the \grantsponsor{GS501100001809}{National Natural
% Science Foundation of
% China}{https://doi.org/10.13039/501100001809} under Grant
% No.:~\grantnum{GS501100001809}{61273304}
% and~\grantnum[http://www.nnsf.cn/youngscientists]{GS501100001809}{Young
% Scientists' Support Program}.

%\subsection{Bibliography}
%\label{sec:ug_bibliography}
%
% The ACM uses the |natbib| package for formatting references and
% the Bib\TeX\ style file \path{ACM-Reference-Format.bst} for Bib\TeX\
% processing. You can disable loading of |natbib| using the
% option |natbib=false| in \cs{documentclass}. However, it is not
% recommended, as well as the use of Bib\TeX\ styles other than
% \path{ACM-Reference-Format.bst}, and may delay the processing of the
% manuscript.
%
%
% \DescribeMacro{\citestyle}%
% If you use |natbib|, you can select one of two predefined citation
% styles using the command \cs{citestyle}: the author-year format
% |acmauthoryear| or the numeric format |acmnumeric|. For example,
% \begin{verbatim}
% \citestyle{acmauthoryear}
% \end{verbatim}
% Note that numeric citations are the default mode for most formats.
%
% \DescribeMacro{\setcitestyle}%
% You can further customize |natbib| using
% the \cs{setcitestyle} command, for example,
% \begin{verbatim}
% \setcitestyle{numbers,sort&compress}
% \end{verbatim}
%
% One of the more common versions is
% \begin{verbatim}
% \setcitestyle{nosort}
% \end{verbatim}
% It is useful if you do not like the way |natbib| sorts citation
% lists.
%
% If you use |natbib|, then commands like \cs{citep} and
% \cs{citeauthor} are automatically supported. The command
% \cs{shortcite} is the same as \cs{cite} in numerical mode and cites
% the year in author-date mode.
%
% Note that before version~1.48 the command \cs{citeyear} put the year
% in parentheses. In version~1.48 and later it produces just the
% year; the command \cs{citeyearpar} can be used to emulate its old
% behavior.
%
% There are several customized \BibTeX\ entry types and fields in the ACM
% style file \path{ACM-Reference-Format.bst} that you may want to be
% aware of.
%
% The style supports the fields \path{doi} and \path{url}, for example,
% \begin{verbatim}
% doi = "10.1145/1188913.1188915",
% url = "http://ccrma.stanford.edu/~jos/bayes/bayes.pdf",
% \end{verbatim}
%
% The style supports the arXiv-recommended fields \path{eprint} and
% (optionally) \path{primaryclass}, for example,
% \begin{verbatim}
% eprint = "960935712",
% primaryclass = "cs",
% \end{verbatim}
% See the examples at \url{http://arxiv.org/hypertex/bibstyles/}.
%
% There are the special entry types \path{online} and
% \path{game} for Web pages and games, for example,
% \begin{verbatim}
% @online{Thornburg01,
% author = "Harry Thornburg",
% year = "2001",
% title = "Introduction to Bayesian Statistics",
% url = "http://ccrma.stanford.edu/~jos/bayes/bayes.html",
% month = mar,
% lastaccessed = "March 2, 2005",
% }
% \end{verbatim}
% For these entry types you can use the \path{lastaccessed} field to add
% the access date for the URL.
%
% There are two ways to enter video or audio sources in the
% bibliograpy corresponding to two different possibilies. For
% standalone sources available online, you can use an \path{online}
% entry and set its \path{howpublished} field. For example,
% \begin{verbatim}
% @online{Obama08,
% author = "Barack Obama",
% year = "2008",
% title = "A more perfect union",
% howpublished = "Video",
% day = "5",
% url = "http://video.google.com/videoplay?docid=6528042696351994555",
% month = mar,
% lastaccessed = "March 21, 2008",
% }
% \end{verbatim}
%
% For sources available as attachments to conference proceedings
% and similar documents, you can use the usual \path{inproceedings}
% entry type and set its \path{howpublished} field:
% \begin{verbatim}
% @Inproceedings{Novak03,
% author = "Dave Novak",
% title = "Solder man",
% booktitle = "ACM SIGGRAPH 2003 Video Review on Animation theater Program",
% year = "2003",
% publisher = "ACM Press",
% address = "New York, NY",
% pages = "4",
% month = "March 21, 2008",
% doi = "10.9999/woot07-S422",
% howpublished = "Video",
% }
% \end{verbatim}
%
% Sometimes you need to cite a complete issue of a journal. The
% \path{periodical} entry type is intended for this:
% \begin{verbatim}
% @periodical{JCohen96,
% key = "Cohen",
% editor = "Jacques Cohen",
% title = "Special issue: Digital Libraries",
% journal = "Communications of the {ACM}",
% volume = "39",
% number = "11",
% month = nov,
% year = "1996",
% }
% \end{verbatim}
%
% If you do not know the year of publication, the style will add
% ``[n. d.]'' (for ``no date'') to the entry.
%
% If you do not know the author (this is often the case for online
% entries), use the |key| field to add a key for sorting and citations,
% for example,
% \begin{verbatim}
% @online{TUGInstmem,
% key = {TUG},
% year = 2017,
% title = "Institutional members of the {\TeX} Users Group",
% url = "http://wwtug.org/instmem.html",
% lastaccessed = "May 27, 2017",
% }
% \end{verbatim}
%
%
%
%\subsection{Colors}
%\label{sec:ug_colors}
%
% While printed ACM publications are usually black and white, |screen|
% mode allows the use of colors. The ACM classes pre-define several
% colors according to~\cite{ACMIdentityStandards}: |ACMBlue|,
% |ACMYellow|, |ACMOrange|, |ACMRed|, |ACMLightBlue|, |ACMGreen|,
% |ACMPurple| and |ACMDarkBlue|. You can use them in color
% assignments.
%
% The ACM provides the following recommendation on color use.
%
% The most accessible approach would be to ensure that your article is
% still readable when printed in greyscale. The most notable reasons
% for this are:
% \begin{enumerate}
% \item The most common type of inherited Color Vision Deficiency
% (CVD) is red-green (in which similar-brightness colors that differ
% only in their amounts of red or green are often confused), and it
% affects up to 8\% of males and 0.5\% of females of Northern European
% descent.
% \item The most common type of acquired Color Vision Deficiency (CVD)
% is blue-yellow (including mild cases for many older adults).
% \item Most printing is in black and white.
% \item Situational impairments (e.g., bright sunlight shining on a
% mobile screen) tend to reduce the entire color gamut, reducing color
% discriminability.
% \end{enumerate}
%
% \textbf{Note:} It is \emph{not} safe to encode information using
% only variations in color (i.e., only differences in hue and/or
% saturation) as there is bound to be someone affected!
%
% To ensure that you are using the most accessible colors, the ACM
% recommends that you choose sets of colors to help ensure suitable
% variations in when printed in greyscale by using either of the following tools:
% \begin{enumerate}
% \item ColourBrewer: \url{http://colorbrewer2.org/}
% \item ACE: The Accessible Colour Evaluator:
% \url{http://daprlab.com/ace/} for designing WCAG 2.0 compliant
% palettes.
% \end{enumerate}
%
%
%\subsection{Other notable packages and typographic remarks}
%\label{sec:ug_other}
%
% Several other packages are recommended for specialized tasks.
%
% The package |subcaption|~\cite{Sommerfeldt13:Subcaption} is
% recommended for complex figures with several subplots or subfigures
% that require separate subcaptioning. The packages
% |nomencl|~\cite{Nomencl} and
% |glossaries|~\cite{Talbot16:Glossaries} can be used for the
% automatic creation of the lists of symbols and concepts used.
%
%
% By default |acmart| prevents all widows and orphans (i.e., lonely
% lines at the beginning or end of the page) and hyphenation at
% the end of the page. This is done by the rather strict settings
% \begin{verbatim}
% \widowpenalty=10000
% \clubpenalty=10000
% \brokenpenalty=10000
% \end{verbatim}
% However, this may lead to frustrating results when the authors must
% obey a page limit. Setting these penalties to smaller values may
% help if you absolutely need to.
%
% Another problem might be the too strict line breaking rules. Again,
% a strategically placed \cs{sloppy} command or putting the
% problematic paragraph inside \texttt{sloppypar} environment might
% help---but beware, the results might be, well, sloppy.
%
% Note that the uppercasing in section titles is done using
% the |textcase| package~\cite{Carlisle04:Textcase}, so the command
% \cs{NoCaseChange} inside the title may help to prevent extraneous
% uppercasing.
%
%\subsection{A note for wizards: \texttt{acmart-preload-hook.tex}}
%\label{sec:ug_preload}
%
% Sometimes you need to change the behavior of |acmart|. The
% usual way to do this is to redefine commands in the preamble.
% However, these definitions are executed \emph{after} |acmart| is
% loaded and certain decisions are made. This presents a number of
% problems.
%
% For example, one may want to use the |titletoc| package with |acmart|.
% This package should be loaded before |hyperref|. However, since
% |acmart| loads |hyperref| itself, the line |\usepackage{titletoc}|
% in the preamble will lead to grief (see
% \url{http://tex.stackexchange.com/questions/357265/using-titletoc-with-acm-acmart-style}).
%
% Another example is passing options to a package. Suppose you want to
% use the |dvipsnames| option of the |xcolor| package. Normally you cannot do
% this because |acmart| loads this package itself without options.
%
% The file |acmart-preload-hook.tex| can be used to solve these
% problems. If this file exists, it will be processed before any other
% package. You can use this file to load packages or pass options to
% them. For example, if you put in this file
% \begin{verbatim}
% \let\LoadClassOrig\LoadClass
% \renewcommand\LoadClass[2][]{\LoadClassOrig[#1]{#2}%
% \usepackage{titletoc}}
% \end{verbatim}
% then |titletoc| will be loaded before |hyperref|. If you put in
% this file
% \begin{verbatim}
% \PassOptionsToPackage{dvipsnames}{xcolor}
% \end{verbatim}
% you will pass |dvipsnames| to |xcolor|.
%
% \textbf{Important note.} This hook makes it too easy to create a
% manuscript that is not acceptable by the ACM. It is even easier to
% create a file that cannot be compiled. So please do not use it
% \emph{unless you know what you are doing.} And if you use it,
% \emph{do not ask for support.} If you decide to use this hook, you
% are on your own.
