This paper describes concepts and features of a Web-based system called XRL/flower for carrying out Petri-net based workflows described with XRL (eXchangeable Routing Language). XR...
Abstract. State space explosion is the hardest challenge to the effective application of model checking methods. We present a new technique for achieving drastic state space reduct...
We present a novel approach which facilitates formal verification of component-based software application families using model checking. This approach enables effective composition...
Abstract. Bisimulation reduction is a classical means to fight the infamous state space explosion problem, which limits the applicability of automated methods for verification li...
