Abstract

leanK 2.0 implements an extension of the “Free Variable Tableaux for Propositional Modal Logics” reported by us in [1]. It performs depth first search and is based upon the original leanTAP prover of Beckert and Posegga [2]. Formulae annotated with labels containing variables capture the universal and existential nature of the box and diamond modalities, respectively, with different variable bindings closing different branches. Prolog’s built-in clause indexing scheme, unification facilities and built-in backtracking are used extensively.
