AI beats Stratego's greatest player, ending one of the last human strongholds in board games

An artificial intelligence system called Ataraxos has defeated the world's top-ranked Stratego player, marking a major milestone for machine learning in imperfect-information games. Unlike chess or Go where all pieces are visible, Stratego requires players to make decisions based on hidden information and bluffing. This victory demonstrates that researchers from Carnegie Mellon, NYU, Stanford, and MIT have successfully developed algorithms capable of managing uncertainty and deception, areas where previous high-profile AI projects had struggled to achieve consistent success against human experts.
