Abstract : We study different languages for representing nondeterministic actions in automated planning from the point of view of knowledge compilation. Precisely, we consider succintness issues (how succinct is the description of an action in each language?) and complexity issues (how hard is it to decide whether a state is a successor of another one through some action described in one of these languages?). We study an abstract, nondeterministic version of PDDL, the language of NNF action theories, and DL-PPA, the dynamic logic of parallel propositional assignments. We show that these languages have different succinctness and different complexity of queries: DL-PPA is the most succinct one and NNF is the least succinct, and deciding successorship is already NP-complete for nondeterministic PDDL.
