WebPolymatrix games are a class of succinctly represented n-player games: a polymatrix game is speci ed by at most n2 bimatrix games, each of which can be written down in quadratic space with respect to the number of strategies. This is unlike general n-player strategic form games, which require a represen- WebJun 11, 2024 · More than two agents: Multiple agents can interact via arbitrary networks of zero-sum polymatrix games and their affine variants. Our results come in stark contrast with the standard interpretation of the behavior of MWU (and more generally regret minimizing dynamics) in zero-sum games, which is typically referred to as "converging to equilibrium".
