FMLtoHOL (version 1.0): Automating First-order Modal Logics with LEO-II and Friends

Abstract

A converter from first-order modal logics to classical higherorder logic is presented. This tool enables the application of off-the-shelf higher-order theorem provers and model finders for reasoning within firstorder modal logics. The tool supports logics K, K4, D, D4, T, S4, and S5 with respect to constant, varying and cumulative domain semantics.
