MAPLE: Multi-State Aggregated Policy Evaluation for AlphaZero in Imperfect-Information Games
arXiv:2605.24139v1 Announce Type: cross Abstract: Imperfect-information games (IIGs) are challenging, as players must make decisions without fully observing the true game state. While AlphaZero has achieved remarkable success in perfect-information games, extending it to IIGs remains difficult. Existing search-based approaches, such as Perfect Information Monte Carlo (PIMC), suffer from strategy fusion, while Information Set Monte Carlo Tree Search (IS-MCTS) incurs high computational cost when combined with neural networks. In this paper, we propose Multi-State Aggregated PoLicy Evaluation (MA
The continuous drive to push AI capabilities beyond perfect-information environments to more complex, real-world scenarios makes advancements in imperfect-information games timely.
This development incrementally advances AI's ability to operate in environments with incomplete knowledge, which is crucial for applications in intelligence, strategy, and complex decision-making.
The proposed MAPLE method offers a more efficient and effective approach to policy evaluation for AlphaZero-like systems in imperfect-information games, overcoming limitations of previous methods.
