Temporal Reasoning with Constraints on Fluents and EventsEddie Schwalb (firstname.lastname@example.org), Kalev Kask (email@example.com) & Rina Dechter (firstname.lastname@example.org)
We propose a propositional language for temporal reasoning that is computationally effective yet expressive enough to describe information about fluents, events and temporal constraints. Although the complete inference algorithm is exponential, we characterize a tractable core with limited expressibility and inferential power. Our results render a variety of constraint propagation techniques applicable for reasoning with constraints on fluents.
