How Alphabet's DeepMind used a 1999 video game to teach its AI teamwork

DeepMind, an Alphabet subsidiary, announced Tuesday its efforts to create an artificial intelligence (AI) that functions with human-like performance. Using Quake III Arena's Capture the Flag (CTF), a 3D first-person multiplayer video game, DeepMind taught AI how to work with and against humans to win the game. The rules of CTF haven't changed much since gym class. Two groups of individuals band together to steal the opponent's flag from their territory while also protecting their own. Teams can tag opponents that enter their territory, sending them back to their respective home base.
