After go and poker, an AI imposes itself in Diplomacy, the game of betrayal between friends

The parent company of Facebook has designed an artificial intelligence capable of playing — and winning — the most deceitful board game in history: Diplomacy.

Researchers from Meta, the parent company of Facebook, have developed an AI called Cicero that combines natural language recognition and strategy algorithms to beat humans in the game Diplomacy. Published on November 22, 2022 in Sciencethe results of this experiment show that Cicero managed to place first in an online tournament.

Why is this interesting. Since the defeat of Gary Kasparov in chess once morest the computer Deep Blue in 1996, artificial intelligence has continued to gain territory once morest human opponents: in Jeopardy in 2011, in go in 2015, in poker in 2019. An extension of the field of the struggle which is now reaching politics and negotiation.

The essential. Diplomacy is a game of taking control of Europe by moving pieces. Its particularity is that each phase of movement is preceded by negotiations, makeshift alliances… often followed by betrayals. A good way to lose friends.

In their experience, the Meta researchers managed to reproduce the very human intricacies of these negotiations, mixing trust and misinformation, cooperation and competition.

By rising to the top of a Diplomacy tournament without being detected by players as a program, Cicero (who was playing anonymously) appears to have passed a form of Turing test — assessing a machine’s ability to imitate human conversation from indistinguishable way.
