DeepMind's AI has now outcompeted nearly all human players at StarCraft II

Taking inspiration from the way pro StarCraft II players train with one another, the researchers instead programmed one of the algorithms to expose the flaws of the other rather than maximize its own chance of winning. "That's kind of [like] asking a friend to play against you," said Oriol Vinyals, the lead researcher on the project, on the call. "These friends should show you what your weaknesses are, so then eventually you can become stronger." The method produced much more generalizable algorithms that could adapt to a broader range of game scenarios.
