### A complete resolution-like calculus for Maxsat

Seminar Room 1, Newton Institute

#### Abstract

Max-SAT is the problem of finding an assignment minimizing the number of unsatisfied clauses of a given CNF formula. We propose a resolution-like calculus for Max-SAT and prove its soundness and completeness. We also prove the completeness of some refinements of this calculus. From the completeness proof we derive an exact algorithm for Max-SAT and a time upper bound. Joint work with Jordi Levy and Felip Manya.
