KeyBanc维持CareTrust REIT股票评级，看好其英国收购计划

2026年9月，麻省理工学院等机构公布博弈人工智能系统Ataraxos，在信息不完全的战略棋类游戏中展现出较强能力。与双方棋子身份完全公开的国际象棋不同，Stratego要求玩家推断对手隐藏棋子的等级，并在试探、保密和风险之间作出选择，因此被用于研究复杂决策。

系统先通过自我对弈学习基础策略，再在每一步行动前利用生成模型估计当前棋盘的可能状态，动态修正选择。研究团队报告，其训练样本需求不到对比系统的百分之一，自我对弈局数不到三十分之一，仍取得更强的游戏表现。系统也被扩展到其他规则不同的信息不完全游戏中。研究的意义在于提高有限计算资源下的推理效率，并为谈判或网络安全等场景提供算法思路。游戏环境拥有清晰规则和评价标准，现实任务则更复杂，团队下一步希望加强决策解释与审查能力，让人类能够理解模型为何给出某项建议。
