SAT-Based Decision Procedures for Normal Modal Logics: A Theoretical Framework

چکیده

Tableau systems are very popular in AI for their simplicity and versatility. In recent papers we showed that tableau-based procedures are intrinsically ineecient, 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 state-of-the-art tableau-based systems. In this paper we provide the theoretical foundations for developing SAT-based decision procedures for many diierent modal logics.

Modal Satisfiability via SMT Solving

Modal logics extend classical propositional logic, and they are robustly decidable. Whereas most existing decision procedures for modal logics are based on tableau constructions, we propose a framework for obtaining decision procedures by adding instantiation rules to standard SAT and SMT solvers. Soundness, completeness, and termination of the procedures can be proved in a uniform and elementa...

More Evaluation of Decision Procedures for Modal Logics

This paper follows on previous papers which presented and evaluated various decision procedures for modal logics. It connrms previous experimental results in showing that SAT based decision procedures, i.e., the procedures built on top of decision procedures for propositional satissability, are more ef-cient than tableau based decision procedures. It also connrms previous evidence of an easy-ha...
