有哪些算法可以解决井字游戏?特别是电路板尺寸为 4 * 4 或更大而不是 3 * 3?我尝试了 4 * 4 与 Minimax 和 alpha-beta 修剪,但 pc 似乎挂起并在堆栈溢出时抛出异常。我看到了这些用 javascript 编写的源代码,但我不知道它使用哪种算法,有人可以为我澄清一下吗? http://js-x.com/page/javascripts__example.html?view=153

尝试在一定深度进行截断...我认为您不需要超过 4 或 5 的深度即可做出完美的移动。
(java for 3*3 one-dim board with depth):
int minimax(int turn, int depth) { // turn(side to move) is 1 or -1
int val = -turn; // worst value for that turn
int result = NULVAL;
if (wins()) return turn; // evaluate board (board is a field)
if (depth == 0) return DRAW;
for (int i = 0; i < 9; i++) {
if (board[i] == EMPTY) {
board[i] = turn; // make move
result = minimax(-turn, depth - 1);
board[i] = EMPTY; // delete move
if (result == turn)
return turn; // sees win
if (result == DRAW)
val = result;
}
}
// if result keeps NULVAL: couldn't make a move (board is full)
if (result == NULVAL) return DRAW;
return val;
}
