Abstract: We introduce Strategy Logic with Knowledge, a novel formalism to reason about knowledge and strategic ability in memoryless multi-agent systems with incomplete information. We exemplify its expressive power; we define the model checking problem for the logic and show that it is PSpace-complete . We propose a labelling algorithm for solving the verification problem that we show is amenable to symbolic implementation. We introduce , an extension of the open-source model checker MCMAS, implementing the proposed algorithm. We report the benchmarks obtained on a number of scenarios from the literature, including the dining cryptographers protocol.
