This game-playing AI is the new champ at Stratego
AI Summary: Researchers developed an AI system that defeated top-ranked human players of the board wargame Stratego, which involves hidden information, by a large margin. The AI system combined efficient training algorithms with new techniques for calculated decision-making in hidden information settings, achieving greater performance while being cheaper and less computationally demanding to train. The system can be generalized for various use-cases, including real-world problems like business negotiations or cybersecurity, and can handle imperfect information tasks where parties possess information others do not. The research, published in Nature, was conducted by researchers from MIT, Carnegie Mellon University, New York University, and Stanford University.
