Researchers are developing new methods to tackle complex games with imperfect information. One paper introduces Recurrent Structural Policy Gradient (RSPG), a novel approach for partially observable mean field games that shows faster convergence than existing methods. Another study re-evaluates policy gradient methods, finding that simpler algorithms like PPO can be competitive with or superior to more complex techniques traditionally used for imperfect-information games. A third paper proposes MAPLE, a tree search method designed to improve AlphaZero's performance in imperfect-information games by aggregating evaluations from multiple sampled world states, demonstrating significant Elo improvements in games like Phantom Go and Dark Hex.
