WebI am using minimax algorithm (for now without alpha beta pruning) for AI in tic tac toe game in Python and Numpy. It's working, but very slow, so I would like to optimize it. Player wins when he has 3 symbols (X or O) in row, column or diagonal, Empty field is represented by 0, X by 1 and O by 2. There is no whole game for performance testing.
