Abstract

Tableau systems are very popular in AI for their simplicity and versatility. In recent papers we showed that tableau-based procedures are intrinsically inefficient, and proposed an alternative approach of building decision procedures on top of SAT decision procedure. We called this approach ‘SAT based’. In extensive empirical tests on the case study of modal K, a SAT-based procedure drastically outperformed a state-of-the-art tableau-based system. In this paper we provide the theoretical foundations for developing SAT-based decision procedures for many different modal logics
