Incomplete MaxSAT solving aims to quickly find a solution that attempts to minimize the sum of the weights of the unsatisfied soft clauses without providing any optimality guarantees. In this paper, we propose two approximation strategies for improving incomplete MaxSAT solving. In one of the strategies, we cluster the weights and approximate them with a representative weight. In another strategy, we break up the problem of minimizing the sum of weights of unsatisfiable clauses into multiple…

TLDR
This paper presents a new algorithm for computing approximate solutions in Θ(N) for the maximum exact 3-satisfiability (MAX-E-3-SAT) problem by using supervised learning methodology and shows that this new algorithm can build assignments better than a random one, even if the convergence of the messages is not found.

Incremental Cardinality Constraints for MaxSAT
TLDR
This paper exploits the knowledge acquired across iterations using novel schemes to use cardinality constraints in an incremental fashion and shows a significant performance boost for these algorithms as compared to their non-incremental counterparts, suggesting that incremental cardinality constraint constraints could be beneficial for other constraint solving domains.
