abstract={Propositional model counting is a classic problem that has
recently witnessed many technical advances and novel applications. While
the basic model counting problem requires computing the number of all
solutions to the given formula, in some important application scenarios,
the desired count is not of all solutions, but instead, of all unique solutions
up to isomorphism. In such a scenario, the user herself must try to
either use the full count that the model counter returns to compute the
count up to isomorphism, or ensure that the input formula to the model
counter adequately captures the symmetry breaking predicates so it can
directly report the count she desires.
We study the use of CNF-level and domain-level symmetry breaking
predicates in the context of the state-of-the-art in model counting, specifically
the leading approximate model counter ApproxMC and the recently
introduced exact model counter ProjMC. As benchmarks, we use
a range of problems, including structurally complex specifications of software
systems and constraint satisfaction problems. The results show that
while it is sometimes feasible to compute the model counts up to isomorphism
using the full counts that are computed by the model counters,
doing so suffers from poor scalability. The addition of symmetry breaking
predicates substantially assists model counters. Domain-specific predicates
are particularly useful, and in many cases can provide full symmetry
breaking to enable highly efficient model counting up to isomorphism.
We hope our study motivates new research on designing model counters
that directly account for symmetries to facilitate further applications of
model counting.
