In games such as Go and chess, players have perfect information, meaning they have access to the full game state (the board and the positions of the pieces). Moreover, there lacks an element of chance that can affect the game state; only the players' decisions can affect the board. Such games are also referred to as perfect-information games. In perfect-information games, it is theoretically possible to enumerate all possible game states. As discussed earlier, this would look such as a tree, where each child node (a game state) is a possible outcome of the parent. In two-player games, alternating levels of this tree represent moves produced by the two competitors. Finding the best possible move for a given state is ...
