Best ResponseYou've already chosen the best response.1It is an adversarial search algorithm used commonly for machine playing of twoplayer games (Tictactoe, Chess, Go, etc.). It stops completely evaluating a move when at least one possibility has been found that proves the move to be worse than a previously examined move. Such moves need not be evaluated further. When applied to a standard minimax tree, it returns the same move as minimax would, but prunes away branches that cannot possibly influence the final decision.

Best ResponseYou've already chosen the best response.1Pseudocode: function alphabeta(node, depth, α, β, Player) if depth = 0 or node is a terminal node return the heuristic value of node if Player = MaxPlayer for each child of node α := max(α, alphabeta(child, depth1, α, β, not(Player) )) if β ≤ α break (* Beta cutoff *) return α else for each child of node β := min(β, alphabeta(child, depth1, α, β, not(Player) )) if β ≤ α break (* Alpha cutoff *) return β (* Initial call *) alphabeta(origin, depth, infinity, +infinity, MaxPlayer)

Best ResponseYou've already chosen the best response.1Thus, when any new node is being considered as a possible path to the solution, it can only work if: alpha <= N <= beta
