Our concern in this paper is with conjecturing diagnoses to explain what happened to a system, given a theory of system behaviour and some observed (aberrant) behaviour. We charac...
Abadi and Cardelli have recently investigated a calculus of objects [2]. The calculus supports a key feature of object-oriented languages: an object can be emulated by another obj...
The frame problem was originally de ned in the context of the situation calculus. The problem also manifests itself in more sophisticated temporal logics that can represent interv...
A complete and decidable propositional logic for reasoning about states of probabilistic sequential programs is presented. The state logic is then used to obtain a sound Hoare-styl...
The Inst-Gen-Eq method is an instantiation-based calculus which is complete for first-order clause logic modulo equality. Its distinctive feature is that it combines first-order ...
