N2 - Annotated Probabilistic Temporal (APT) logic programs are a form of logic programs that allow users to state (or systems to automatically learn) rules of the form "formula G becomes true K time units after formula F became true with L to U% probability." In this paper, we develop a theory of abduction for APT logic programs. Specifically, given an APT logic program II, a set of formulas H that can be "added" to II, and a goal G, is there a subset S of H such that II U S is consistent and entails the goal G? In this paper, we study the complexity of the Basic APT Abduction Problem (BAAP). We then leverage a geometric characterization of BAAP to suggest a set of pruning strategies when solving BAAP and use these intuitions to develop a sound and complete algorithm.
