Bit vectors and bit operations are proposed for efficient propositional inference. Bit arithmetic has efficient software and hardware implementations, which can be put to advantage...
We developed an importer from both HOL 4 and HOL-light into Isabelle/HOL. The importer works by replaying proofs within Isabelle/HOL that have been recorded in HOL 4 or HOL-light a...
Abstract. This paper presents a technique for automated theorem proving with free variable tableaux that does not require backtracking. Most existing automated proof procedures usi...
A boolean formula in conjunctive normal form (CNF) F is refuted by literal?once resolution if the empty clause is inferred from F by resolving on each literal of F at most once. Li...
Abstract. This is a theoretical paper giving the extended Stone duality perspective on the recently discovered connection between duality theory as studied in non-classical logic a...
