Abstract: | Theorem 16 in [Piero A. Bonatti, Reasoning with infinite stable models, Artificial Intelligence 156 (1) (2004) 75-111] states that ground skeptical and credulous inferences under the stable model semantics are decidable when the given normal logic program is finitary. Giovanni Criscuolo and Nicola Leone independently observed in personal communications that the proof of this theorem relies on an unproved assumption that—at the best of our current knowledge—might turn out to be false. In this note we correct Theorem 16 by adding the set of odd-cyclic atoms to the inputs of the computation, and argue that this change has no impact on the current applications of the theory of finitary programs. |
