AI becomes grandmaster in ‘fiendishly complex’ StarCraft II | THE GUARDIAN

Top players need adaptable short and long-term strategies to grow and defend their bases while laying waste to the opposition. To complicate matters, players cannot see the whole “map” of the game, so decisions are made on partial information.

With 44 days of training, an AI model from DeepMind outperformed 99.8% of human players at StarCraft II, a sophisticated e-sport game widely believed to be at the outer edges of human mastery. The GUARDIAN reports the achievement was the next ‘grand challenge’ after chess, Go, and poker, all games where AI systems have shown superior play.

  • The number of possible moves at any one point is 10 to the 26th power
  • The Deep Mind system, named AlphaStar, was deliberately slowed so it couldn’t win by its calculating speed alone. Instead it had to learn the strategy of play.
  • The research has implications for advances in areas such as self-driving cars, personal assistants, weather and climate modelling, and other applications involving complexity
