WebNP-complete [13, 5].) Since NP-completeness is not an option, to understand the complexity of Nash one must essentially start all over in the path that led us to NP-completeness: We must de ne a class of problems which contains, along with Nash, some other well-known hard problems, and then prove that Nash is complete for that class.

What interesting problem can you possibly reduce Chess or Go to? Chess is just chess; Go is just Go. The state-space complexity of a game is the number of legal game positions reachable from the initial position of the game. When this is too hard to calculate, an upper bound can often be computed by also counting (some) illegal positions, meaning positions that can never arise in the course of a game. The game tree size is the total number of possible games that can be played: the number of leaf …
