Я пытаюсь сделать игру с минимаксом ti c -ta c -Tee, потому что я новичок в Python и пытаюсь понять, как работает простая игра AI-mini-max. ИИ по какой-то причине все еще идет в том порядке, в котором пятно появляется в списке для доски.
Пример: если верхнее правое пятно было первым в списке "b", оно выбирает его первым. Похоже, что он рассчитывает баллы, но я не думаю, что он использует их по какой-то причине. Я хочу, чтобы это не go в порядке того, что места на доске. Я не могу найти способ заменить код, который помещает "O".
