Predicate abstraction has been proved effective for verifying several infinite-state systems. In predicate abstraction, an abstract system is automatinstructed given a set of predi...
Abstract. We present an extrapolation with care set operator to accelerate termination of reachability computation with polyhedra. At the same time, a counterexample guided refine...

Abstract. We present a new open source model checker, opaal, for automatic verification of models using lattice automata. Lattice automata allow the users to incorporate abstracti...
Abstract. We consider the termination problem of programs manipulating treelike dynamic data structures. Our approach is based on a counter-example guided ion refinement loop. We ...
