![]() ![]() Notably, say the authors, this performance was achieved without deploying any search methods, a key ingredient for many milestone AI achievements in board games in past. It won against all bots and achieved a highly competitive level of play against human expert Stratego players on Gravon, an internet gaming platform and the largest online platform for Stratego. DeepNash was tested against various state-of-the-art Stratego bots and human expert players. At the core of DeepNash is a reinforcement learning algorithm, “R-NaD.” To make DeepNash, Perolat and team combined R-NaD with a deep neural network architecture to learn a strategy that plays at a highly competitive level. This new method resulted in a bot called DeepNash that achieved human expert-level performance in the most complex variant of the game, Stratego Classic. Lead entire armies across the battlefields of Europe during World War 2 or dive headfirst into a skirmish between roaming packs of ninjas during the Edo Period in Japan in these multiplayer strategy games. Here, Julien Perolat and colleagues introduce a novel method that allows an AI for learning to play the game. Currently, it is not possible to use imperfect information search techniques to master Stratego. An “imperfect” information game (in which some aspect of play is hidden from opponents), Stratego poses key challenges to AI researchers because of the many complex aspects of its structure, including having more possible states than another well-researched imperfect information game: no-limit Texas Hold’em poker. There are a number of versions, but still the most popular is the standard version of the game. For many years, the Stratego board game – which tests one’s ability to make relatively slow, deliberative, and logical decisions sequentially – has constituted one of the next frontiers of AI research. This is the original format for the game. This represents an “extraordinary result that the Stratego community did not believe would have been possible with current techniques,” say the study’s authors. The 9th round of the 6th Stratego WCO vs maxroelofs.Not one of my best games, but still keen to see what you guys think of the game and what I could have don. But Stratego still holds its own (especially in the leaner sci-fi revision I mentioned before). ![]() Lord of the Rings: The Confrontation cut out all the bloat and made a tighter, more interesting game. A newly developed AI agent called “DeepNash” learned to play Stratego, one of the few board games AI has not yet mastered, at a human expert level, researchers report. 'Block' wargames adapted the idea to a broader scope with additional complexity and purpose. ![]()
