arXiv:2605.20577v1 Announce Type: cross Abstract: Riichi Mahjong is a multi-player, imperfect-information game characterized by stochasticity and high-dimensional state spaces. These attributes present a unique combination of challenges that mirror complex real-world decision-making problems in reinforcement learning. While prior research has heavily relied on supervised learning from human play logs to pre-train the policy, algorithms capable of learning \textit{tabula rasa} (from scratch) offer greater potential for general applicability, as evidenced by the AlphaZero lineage. To facilitate
The development of GPU-accelerated simulators like Mahjax is a natural progression as researchers push for more efficient and robust reinforcement learning environments for complex, imperfect-information games.
This work demonstrates a continued push towards training AI agents from scratch in high-dimensional, stochastic environments, moving beyond reliance on human data.
The availability of efficient, GPU-accelerated simulation tools like Mahjax lowers the barrier to entry for developing and testing advanced reinforcement learning algorithms for complex game AI.
