Abstract [en]: In this paper we analyze the complexity of the language A, proposed in [Gelfond and Lifschitz, 1993] to formalize properties of actions. We prove that the general language is NP complete, thus intractable, and show some tractable (polynomial) subclasses of it. We also show how states that are unreachable affect the semantics of the language.
