Subsequently, he refined the technique until he reached a balance between what he should follow and what he should not follow. Also his ability to influence the decisions of third parties.

Before rolling it out online, the research team responsible for its AI fed the system thousands of game data from diplomacy. A total of 125,261 anonymous games, 40,000 dialogues and 12 million messages.
