Generalized Weighted Model Counting: An Efficient Monte-Carlo meta-algorithm (Working Paper) [chapter]

Lirong Xia
2012 Lecture Notes in Computer Science  
This problem turns out to be a natural extension of the weighted model counting (WMC) problem [15] , which we call generalized weighted model counting (GWMC) problem.  ...  Based on importance sampling, we propose a Monte-Carlo meta-algorithm that has a good theoretical guarantee for formulas in disjunctive normal form (DNF).  ...  Summary and Future Work In this paper, we propose an efficient Monte-Carlo meta-algorithm to compute GWMC for DNF formulas, motivated by applications in pricing combinatorial prediction markets.  ...
