Abstract, We consider the problem of integrating Reiter's default logic into terminological representation systems. It turns out that such an integration is less straightforwa...
We explore the possibility of a logic where a conclusion substantially improves over its premise(s): Specifically, we intend to rule out inference steps such that the premise conv...
Transaction Logic is an extension of classical logic that gracefully integrates both declarative and procedural knowledge and has proved itself as a powerful formalism for many ad...
The inverse method is a generic proof search procedure applicable to non-classical logics satisfying cut elimination and the subformula property. In this paper we describe a genera...
Abstract. We give an optimal (exptime), sound and complete tableaubased algorithm for deciding satisfiability for propositional dynamic logic. Our main contribution is a sound meth...
