Alternating-time temporal logic

Alternating-time Temporal Logic (ATL) is a branching-time temporal logic that extends classical temporal logics, such as Computation Tree Logic (CTL), to allow reasoning about the strategic abilities of agents in multi-agent systems. Developed in the early 2000s, ATL incorporates game-theoretic concepts to express not only what is true or false at a particular point in time but also what different agents can achieve through their actions.
