A divide & conquer approach to liveness model checking under fairness & anti-fairness assumptions

Abstract

This paper proposes an approach to making liveness model checking problems under fairness feasible. The proposed method divides such a problem into smaller ones that can be conquered. It is not superior to existing tools dedicated to model checking liveness properties under fairness assumptions in terms of model checking performance but has the following positive aspects: 1) the approach can be used to model check liveness properties under anti-fairness assumptions as well as fairness assumptions, 2) the approach can help humans better understand the reason why they need to use fairness and/or anti-fairness assumptions, and 3) the approach makes it possible to use existing linear temporal logic model checkers to model check liveness properties under fairness and/or anti-fairness assumptions.
