+In work unpublished and independent of ours, Grohe, et. al.~\cite{https://doi.org/10.48550/arxiv.2201.11524} investigate \abbrBPDB\xplural showing a dichotomy for the query evaluation problem over \abbrBPDB\xplural when computing the probability of an output tuple having at most a multiplicity of $k$.  This work allows for unbounded multiplicities and therefore addresses the concern of a succinct representation of the distribution over infinitely many multiplicities.  Our work in contrast assumes a finite bound on the multiplicities where we simply list the finitely many probability values.  The work also observes that computing the expected value of an output tuple multiplicity is in polynomial time, but does not, as this work does, further look into the fine-grained analysis of computing this value.
