Alternating Time Temporal Logic

Alternating-time temporal logic (ATL) is a formal framework for verifying strategic abilities in multi-agent systems, focusing on whether coalitions of agents can achieve goals despite the actions of other agents. Current research emphasizes extending ATL's capabilities to handle richer semantics, such as imperfect information, multiple truth values, and the comparison of strategic interactions, often employing techniques like SAT-based solvers, assume-guarantee reasoning, and model-dependent reductions to manage the computational complexity. These advancements improve the applicability of ATL to complex real-world scenarios, including the verification of multi-agent systems in areas like cybersecurity and robotics.
