In computer science, Alternating-time Temporal Logic, or ATL, is a branching-time temporal logic that naturally describes computations of multi-agent system and multiplayer games. It offers selective quantification over program-paths that are possible outcomes of games. ATL uses alternating-time formulas to construct model-checkers in order to address problems such as receptiveness, realizability, and controllability.
