MaxSolver: An efficient exact algorithm for (weighted) maximum satisfiability
Maximum Boolean satisfiability (max-SAT) is the optimization counterpart of Boolean satisfiability (SAT), in which a variable assignment is sought to satisfy the maximum number of clauses in a Boolean formula. A branch and bound algorithm based on the Davis-Putnam-Logemann-Loveland procedure (DPLL) is one of the most competitive exact algorithms for solving max-SAT. In this paper, we propose an...
متن کاملCCEHC: An Efficient Local Search Algorithm for Weighted Partial Maximum Satisfiability (Extended Abstract)
Weighted partial maximum satisfiability (WPMS) is a significant generalization of maximum satisfiability (MAX-SAT), with many important applications. Recently, breakthroughs have been made on stochastic local search (SLS) for weighted MAXSAT and (unweighted) partial MAX-SAT (PMS). However, the performance of SLS for WPMS lags far behind. In this work, we present a new SLS algorithm named CCEHC ...

Maximum Boolean satisfiability (max-SAT) is the optimization counterpart of Boolean satisfiability (SAT), in which a variable assignment is sought to satisfy the maximum number of clauses in a logical formula. A branch-and-bound algorithm based on the Davis-PutnamLogemann-Loveland procedure (DPLL) is one of the most efficient complete algorithms for solving max-SAT. In this paper, We propose an...
متن کاملSparse Message Passing Algorithms for Weighted Maximum Satisfiability
Weighted maximum satisfiability is a wellstudied problem that has important applicability to artificial intelligence (for instance, MAP inference in Bayesian networks). General-purpose stochastic search algorithms have proven to be accurate and efficient for large problem instances; however, these algorithms largely ignore structural properties of the input. For example, many problems are highl...
متن کاملBackbone Guided Local Search for the Weighted Maximum Satisfiability Problem
The Satisfiability problem (SAT) is a famous NP-Complete problem, which consists of an assignment of Boolean variables (true or false) and some clauses formed of these variables. A clause is a disjunction of some Boolean literals and can be true if and only if any of them is true. A SAT instance is satisfied if and only if all the clauses are simultaneously true. As a generalization of SAT, the...
