Reachability problems for cyclic protocols
Hong Liu, Raymond E. Miller · 2002
We study three reachability problems for cyclic protocols: (1) global state reachability; (2) abstract state reachability; and (3) execution cycle reachability. By combining fair progress and maximal progress during state exploration, we prove that these three problems an all decidable for Q, the class of cyclic protocols with finite fair reachable state spaces. In the course of the investigation, we also show that detection of k-indefiniteness and k-livelock an decidable for Q.
