Model-checking is becoming an accepted technique for debugging hardware and software systems. Debugging is based on the “Check / Analyze / Fix” loop: check the system against a...

Shorter counterexamples are typically easier to understand. The length of a counterexample, as reported by a model checker, depends on both the algorithm used for state space explo...
Current stochastic model checkers do not make counterexamples for property violations readily available. In this paper we apply directed explicit state space search to discrete- a...
Disproof can be as important as proof in studying programs and programming languages. In particular, side conditions in a statement about program behavior are sometimes best unders...
