Equivariant Networks for Zero-Shot Coordination
We present a novel equivariant network architecture for use in Dec-POMDPs that prevents the agent from learning policies which break symmetries, doing so more effectively than prior methods.

Is Independent Learning all you need in the Starcraft Multi-Agent Challenge?
We demonstrate that, despite its various theoretical shortcomings, Independent PPO (IPPO), a form of independent learning in which each agent simply estimates its local value function, can perform just as well as or better than state-of-the-art joint learning approaches.
