| Abstract: | ABSTRACT. We describe an implementation of a new theorem prover for Intuitionistic Propositional Logic based on a sequent calculus with histories due to Corsi and Tassi. The main novelty of the prover lies in its use of dependency directed backtracking for global caching. We analyse the performance of the prover, and various optimisations, in comparison to current state of the art theorem provers and show that it produces competitive results on many classes of formulae. |
