We chose to use general-purpose machine learning techniques – including neural networks, self-play via reinforcement learning, multi-agent learning, and imitation learning – to learn directly from game data with general purpose techniques. AlphaStar played on the official game server,, using the same maps and conditions as human players.The League training is fully automated, and starts only with agents trained by supervised learning, rather than from previously trained agents from past experiments.Each of the Protoss, Terran, and Zerg agents is a single neural network. AlphaStar can now play in one-on-one matches as and against Protoss, Terran, and Zerg – the three races present in StarCraft II.AlphaStar now has the same kind of constraints that humans play under – including viewing the world through a camera, and stronger limits on the frequency of its actions* (in collaboration with StarCraft professional Dario “TLO” Wünsch). ![]() Our new research differs from prior work in several key regards: Since then, we have taken on a much greater challenge: playing the full game at a Grandmaster level under professionally approved conditions. This January, a preliminary version of AlphaStar challenged two of the world's top players in StarCraft II, one of the most enduring and popular real-time strategy video games of all time. Unable to make significant progress.TL DR: AlphaStar is the first AI to reach the top league of a widely popular esport without any game restrictions. However, when trained on the main game, these agents are Mini-games, these agents learn to achieve a level of play that is comparable toĪ novice player. Reinforcement learning agents applied to the StarCraft II domain. Finally, we present initial baseline results for canonical deep We give initial baseline resultsįor neural networks trained from this data to predict game outcomes and playerĪctions. Game replay data from human expert players. For the main game maps, we also provide an accompanying dataset of Provide a suite of mini-games focusing on different elements of StarCraft II ![]() StarCraft II domain and provide an open source Python-based interface forĬommunicating with the game engine. We describe the observation, action, and reward specification for the Space that must be observed solely from raw input feature planes and it hasĭelayed credit assignment requiring long-term strategies over thousands of Involving the selection and control of hundreds of units it has a large state ![]() Information due to a partially observed map it has a large action space Multi-agent problem with multiple players interacting there is imperfect Poses a new grand challenge for reinforcement learning, representing a moreĭifficult class of problems than considered in most prior work. Reinforcement learning environment based on the StarCraft II game.
