Verification of Broadcasting Multi-Agent Systems against an Epistemic Strategy Logic

We study a class of synchronous, perfect-recall multi-agent systems with imperfect information and broadcasting, i.e., fully observable actions. We define an epistemic extension of strategy logic with incomplete information and the assumption of uniform and coherent strategies. In this setting, we prove that the model checking problem, and thus rational synthesis, is non-elementary decidable. We exemplify the applicability of the framework on a rational secret-sharing scenario. This paper has been accepted for publication in the proceedings of the 26th International Joint Conference on Artificial Intelligence (IJCAI 2017).
