Abstract

For a variety of infinite-state systems, the problem of deciding whether a given system is self-stabilizing or not is investigated from the decidability viewpoint. We develop a unified strategy through which checking self-stabilization is shown to be decidable for lossy vector addition systems with states, one-counter machines, and conflict-free Petri nets. For lossy counter machines and lossy channel systems, in contrast, the self-stabilization problem is shown to be undecidable.
