contents	We present two novel symbolic algorithms for model checking the Alternating-time Temporal Logic ATL, over both the infinite-trace and the finite-trace semantics. In particular, for infinite traces we design a novel symbolic reduction to parity games. We implement both methods in the ATLAS model checker and evaluate it using synthetic benchmarks as well as a cybersecurity scenario. Our results demonstrate that the symbolic approach significantly outperforms the explicit-state representation and we find that our parity-game-based algorithm offers a more scalable and efficient solution for infinite-trace verification, outperforming previously available tools. Our results also confirm that finite-trace model checking yields substantial performance benefits over infinite-trace verification. As such, we provide a comprehensive toolset for verifying multiagent systems against specifications in ATL*.
