Abstract. State-based systems and modal logics for reasoning about them often heterogeneously combine a number of features such as non-determinism and probabilities. Here, we show ...
Logic and object-orientation (OO) are competing ways of looking at the world. Both view the world in terms of individuals. But logic focuses on the relationships between individual...
Concurrent Action-Oriented Specifications (CAOS) model the behavior of a synchronous hardware circuit as asynchronous guarded at an abstraction level higher than the Register Tran...
We prove that TAUT has a p-optimal proof system if and only if a logic related to least fixed-point logic captures polynomial time on all finite structures. Furthermore, we show ...
Inconsistencies may arise in the course of specification of systems, and it is now recognised that they cannot be forbidden. Recent work has concentrated on enabling requirements ...
