Question

我试图查看已经存在的Tic Tac Toe代码，并发现有一种名为MiniMax的算法，虽然我已经了解它是如何工作的，但我似乎无法使用5 * 5 Tic Tac Toe表。

我已经知道我将如何做到这一点，但我似乎找不到适合它的方法。

我正在尝试检查1个col / row / diagonals中的每4个移动，以便在那里获胜，或者如果是另一个玩家则有一个阻止。但我似乎无法找到我能做到的，过去6个小时我一直在努力。

#include <iostream>
#include <cstdlib>
#include <time.h>

  char arr[5][5];
char player1 = 'X';
char player2 = 'O';
char player = player1;

  cout << "     1  " << "2  " << "3  "<<"4  "<<"5  " << endl;
  cout << "    ----------------" << endl;
  for (int row = 0; row < 5; row++) {
    cout << row + 1 << " |  ";
    for (int col = 0; col < 5; col++) {
      cout << arr[row][col] << "  ";
    }
    cout << endl;
  }
}
void new_turn();
int firstEmptyRow(int c){
    int i;
    for(i=0;i<5;i++){
        if(arr[i][c])
            return i;
    }

我曾做过类似的事情，但没有使用MiniMax算法。我使用了xkcd的漫画“指南”，讲述了最佳的tic tac toe动作。如果你的程序遵循这个，你永远不会输，只有赢或平。
