Output-determinacy is an important soundness notion in the theory of non-deterministic asynchronous concurrent systems whose alphabet is partitioned into input and output actions. Intuitively, it postulates that the set of enabled outputs of a system must be fully determined by the visible history of its interactions with the environment, as otherwise the specification is contradictory in the sense that it simultaneously requires and forbids some output.In the case of safe or k-bounded Petri nets checking output-determinacy was known to be PSPACE-complete, but the complexity (and even decidability) of this problem for general Petri nets was open. In this paperwe show that the problem of checking whether output-determinacy is violated is decidable and equivalent to reachability in general Petri nets.
