Abstract. The paper presents a novel technique to create implementations of the basic primitives used in symbolic program analysis: forward symbolic evaluation, weakest liberal pre...
—We introduce a new BDD-like data structure called Hybrid-Restriction Diagrams (HRDs) for the representation and manipulation of linear hybrid automata (LHA) state-spaces and pre...
Abstract. We describe a method for synthesizing reasonable underapproximations to weakest preconditions for termination--a long-standing open problem. The paper provides experiment...

Consistency checking in the CSP B approach verifies that an individual controller process, defined using a sequential non-divergent subset of CSP, never calls a B operation outsid...
Recent research has suggested that a large class of software bugs fall into the category of inconsistencies, or cases where two pieces of program code make incompatible assumption...
