Abstract:
SharpSAT-TD is a recently published exact model counter that performed exceptionally well in the recent editions of the Model Counting Competition (https://mccompetition.org/). Notably, it additionally features *weighted* model counting capabilities over any semiring. In this work, we show how to exploit this fact to use SharpSAT-TD as a knowledge compiler to the class of sd-DNNF circuits. Our experimental evaluation shows that the efficiency of SharpSAT-TD for (weighted) model counting transfers to knowledge compilation, since it outperforms other state of the art knowledge compilers on standard benchmark sets. Additionally, we generalized SharpSAT-TD's preprocessing to support arbitrary semirings and consider the utility of auxiliary variables in this setting.
