"Games are used as a test bed for artificial-intelligence techniques simply because of their complexity," said MIT researches SRK Branavan. "Every action that you take in the game doesn't have a predetermined outcome, because the game or the opponent can randomly react to what you do. So you need a technique that can handle very complex scenarios that react in potentially random ways. [Instruction manuals are a] very open text. They don't tell you how to win. They just give you very general advice and suggestions, and you have to figure out a lot of other things on your own."
The AI was able to learn a lot from the manual and its win percentage rose to 79%.
