进入正题,MaxSAT既然是SAT问题的扩展,那么很好理解的是它们之间的结构很相似,都是使用合取范式CNF,但还是有一些细小的规则上的差别。 MaxSAT好就好在,(它好个锤子)它可以分成很多类别,根据MaxSAT竞赛网站 MaxSAT-evaluation 来说,MaxSAT主要分为四大类: 不带权重的MaxSAT (Unweighted MaxSAT) 如果只说MAXSAT,我们...
Experiments show that our solver DeciLS achieves state of the art performance on all unweighted benchmarks from the MaxSAT Evaluation 2016. Moreover, compared to SAT-based MaxSAT solvers which dominate industrial benchmarks for years, it performs better on industrial benchmarks and significantly ...
MaxSAT Evaluation 2017: Solver and Benchmark Descriptions Maxino is based on the k-ProcessCore algorithm, a parametric algorithm generalizing OLL, ONE and PMRES. Parameter k is dynamically determined for each processed unsatisfiable core by a function taking into account the size of the core. R....
there has been no advance allowing to significantly speed up BnB MaxSAT solvers in recent years, as illustrated by their absence in the annual MaxSAT Evaluation since 2017. 译文:可能正是由于这一困难,近年来BnB的MaxSAT解决方案并没有显著提速,从2017年以来的年度MaxSAT评估中就可以看出这一点。 In ...
Many real-life optimization problems can be formulated in Boolean logic as MaxSAT, a class of problems where the task is finding Boolean assignments to variables satisfying the maximum number of logical constraints. Since MaxSAT is NP-hard, no algorithm
被引量: 0发表: 2016年 MAX-SAT 2012: ubcsat-irots For this competition, we submitted a new UBCSAT [2] implementation of Iterated Robust Tabu Search (IROTS) from Smyth, Hoos and St眉tzle [1]. The most significant change to the UBCSAT software framework was the internal representation of...
In this paper we present an extensive empirical evaluation of a number of maxsat solvers. In addition to traditional maxsat solvers, we also evaluate the use of a state-of-the-art Mixed Integer Program (mip) solver, cplex, for solving maxsat. mip solvers are the most popular technology ...
This led WPM2 to achieve the best overall results at the international MaxSAT Evaluation 2013 (MSE13) on industrial instances. Then, we present additional techniques and heuristics to further exploit the information retrieved from the resolution of the subproblems. We exhaustively analyze the impact ...
