Abstract. Applications in software verification often require determining the satisfiability of first-order formulæ with respect to some background theories. During development...
In this paper we propose to extend the current capabilities of automated reasoning systems by making use of techniques from integer programming. We describe the architecture of an ...
The use of approximation as a method for dealing with complex problems is a fundamental research issue in Knowledge Representation. Using approximation in symbolic AI is not strai...
Recently, conditional logics have been developed for application to problems in default reasoning. We present a uniform framework for the development and investigation of conditio...
In this paper we continue investigations of proof theory of default logic. It turns out that, similarly to classical logic, default theories can be represented in normal forms.
