Question

我有一个由纽扣制成的tic tac toe board。每个按钮都链接到启动逻辑的方法。我遇到的问题是，当人类玩家（noughts）轮到他们时，逻辑正在跳过那个回合，运行AI转向然后只回到人类玩家，这次他们正在按预期工作

点击该按钮时，该问题应该调用setText方法并标记为“＆＃39; O＆＃39;对于人类玩家，或者＆＃39; X＆＃39;对于AI。在此之后，按钮被设置为无效，跟踪电路板的阵列会发生变化。

我正在打印日志，从我可以看到，人类用户点击是触发AI移动的内容，而不是自动完成。但我无法说明为什么会这样。我认为我的逻辑存在缺陷，但我无法找出问题所在。编辑：它适用于第一次人工点击，之后就是那个问题。

Answer 1

问题不在于你的逻辑。问题在于如何实施。

您目前拥有一个逐步逻辑系统，其中逻辑中的每个步骤都由receiveClick（View）方法触发。问题是没有自动触发AI转弯。

noughtsTurn = true
receiveClick（View）可以与玩家一起正常工作。
转弯逻辑在playerClick（View）中完成，其中noughtsTurn的值被反转。
问题是什么都没有触发AI转向，下次单击按钮时它会调用receiveClick（View），但noughtsTurn值为false。
即使玩家刚刚点击，这也模拟了AI转向。

你需要在playerClick（View）的末尾添加某种逻辑，这样如果玩家轮到它，就会重新运行AI转向的逻辑。

示例：

public void playerClick(View view) {
    Button B;
    int boardSetIndex;
    int boardSetValue;

    if (view instanceof Button) {
        B = (Button) view;
        if ( noughtsTurn ) {
            B.setText(player.noughtsPlayer());
        } else {
            B = aiPlayerPick();
            System.out.println("AI picked: " + targetIndex);
            B.setText(player.crossesPlayer());
        }
        board.set(boardSetIndex(), boardSetValue());
        System.out.println("Board: " + board);
        B.setEnabled(false);
        //
        if(setTurn(noughtsTurn) == false){
            playNow(findViewByTag(randomButtonPick()))
        }
        //
    }
}

在上面的例子中，有一些关键的东西丢失，例如检查randomButtonPick（）是否已被占用以及setTurn（boolean）返回void而不是布尔值的事实。你需要某种方法来检查玩家是否转了一圈，如果是的话，让AI转一圈。

Answer 2

好的，所以这是我为这个问题找到的最终解决方案。我保持了相同的逻辑，但将人类和AI分离成单独的方法，AI仍然依赖于X = [[ 1, 2], [3, 4], [5, 6], [7, 8]] y = [0, 0, 1, 1] k_fold = 2 for X_train, y_train, X_valid, y_valid in k_fold_generator(X, y, k_fold): # Train using X_train and y_train # Evaluate using X_valid and y_valid方法。
