A Resolution-Based Theorem Prover for $${\textsf {K}}_{n}^{}$$: Architecture, Refinements, Strategies and Experiments

In this paper we describe the implementation of Open image in new window , a resolution-based prover for the basic multimodal logic \({\textsf {K}}_{n}^{}\). The prover implements a resolution-based calculus for both local and global reasoning. The user can choose different normal forms, refinements of the basic resolution calculus, and strategies. We describe these options in detail and discuss their implications. We provide experiments comparing some of these options and comparing the prover with other provers for this logic.
