The state-space complexity of a game is the number of legal game positions reachable from the initial position of the game.

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. Web1 Answer Sorted by: 46 We begin by noting that all NP-complete problems are reducible to 3SAT. Now we have a Turing machine that iterates over all possible assignments, and if a satisfying assignment is not found then it runs forever. This machine halts if and only if the 3SAT instance is satisfiable.
