Guided Local Search for Solving SAT and Weighted MAX-SAT Problems
In this paper, we show how Guided Local Search (GLS) can be applied to the SAT problem and show how the resulting algorithm can be naturally extended to solve the weighted MAX-SAT ...

A Benchmark Method for the Propositional Modal Logics K, KT, S4
A lot of methods have been proposed -- and sometimes implemented -- for proof search in the propositional modal logics K, KT, and S4. It is difficult to compare the usefulness of ...
