We present novel techniques for efficient controller synthesis for untimed and timed systems with respect to invariance and reachability properties. In the untimed case, we give al...
software in the form of abstract classes; and the specification elements of the language can also be used in concrete classes to document the implementations and their development ...
Abstract. Loops and other unbound control structures constitute a major bottleneck in formal software verification, because correctness proofs over such control structures generall...
The B method is one of the most used formal methods, when reactive systems is under question, due to good support for refinement. However, obtaining the formal model from requireme...
