"In other words, capture the flag requires what would seem to be a very human set of skills. But researchers at an artificial intelligence lab in London have shown that machines can master this game, too, at least in the virtual world.DeepMind Can Now Beat Us at Multiplayer Games, Too | NYT
In a paper published on Thursday in Science (and previously available on the website arXiv before peer review), the researchers reported that they had designed automated “agents” that exhibited humanlike behavior when playing the capture the flag “game mode” inside Quake III. These agents were able to team up against human players or play alongside them, tailoring their behavior accordingly.
“They can adapt to teammates with arbitrary skills,” said Wojciech Czarnecki, a researcher with DeepMind, a lab owned by the same parent company as Google."
