This paper introduces a new model checking algorithm that searches for non-progress cycles, used mainly to check for livelocks. The algorithm performs an incremental depth-first search, i.e., it searches through the graph incrementally deeper. It simultaneously constructs the state space and searches for non-progress cycles. The algorithm is more efficient than the method the model checker SPIN currently uses, and finds shortest (w.r.t. progress) counterexamples. Its only downside is the need
more &raquo; ... r a subsequent reachability depth-first search (which is not the bottleneck) for constructing a full counterexample. The new algorithm is better combinable with partial order reduction than SPIN's method.
