In the end, the DeepMind team found that its agents were, on average, able to beat teams of two human players by a margin of 16 captures. “In a separate study, we probed the exploitability of the FTW [For The Win] agent by allowing a team of two professional games testers with full communication to play continuously against a fixed pair of FTW agents,” the researchers wrote. “Even after 12 hours of practice, the human game testers were only able to win 25% (6.3% draw rate) of games against the agent team.”
