We investigate the decidability of the emptiness problem for three classes of distributed automata. These devices operate on finite directed graphs. acting as networks of identical finite-state machines that communicate in an infinite sequence of synchronous rounds. The problem is shown to be decidable in LogSpace for a class of forgetful automata. https://www.spidertattooz.com/The-GelBottle-Inc-Gel-Polish-Audrey-67oz-p17921/
