写一个六子棋棋盘的博弈树代码

好的，我可以回答这个问题。以下是一个六子棋棋盘的博弈树代码的示例：

#include <stdio.h>
#include <stdlib.h>

#define BOARD_SIZE 6
#define MAX_DEPTH 5

typedef struct {
    int x;
    int y;
} Move;

typedef struct {
    int board[BOARD_SIZE][BOARD_SIZE];
    int player;
} GameState;

int evaluate(GameState state) {
    // TODO: 实现评估函数
    return 0;
}

int is_game_over(GameState state) {
    // TODO: 实现判断游戏是否结束的函数
    return 0;
}

Move get_best_move(GameState state, int depth) {
    if (depth == MAX_DEPTH || is_game_over(state)) {
        return (Move) {-1, -1};
    }

    Move best_move = {-1, -1};
    int best_score = -1000000;

    for (int i = 0; i < BOARD_SIZE; i++) {
        for (int j = 0; j < BOARD_SIZE; j++) {
            if (state.board[i][j] == 0) {
                GameState new_state = state;
                new_state.board[i][j] = state.player;
                new_state.player = 3 - state.player;

                int score = -evaluate(new_state);
                Move move = {i, j};

                if (score > best_score) {
                    best_score = score;
                    best_move = move;
                }
            }
        }
    }

    return best_move;
}

int main() {
    GameState state = {
        .board = {
            {0, 0, 0, 0, 0, 0},
            {0, 0, 0, 0, 0, 0},
            {0, 0, 0, 0, 0, 0},
            {0, 0, 0, 0, 0, 0},
            {0, 0, 0, 0, 0, 0},
            {0, 0, 0, 0, 0, 0},
        },
        .player = 1,
    };

    Move best_move = get_best_move(state, 0);

    printf("Best move: (%d, %d)\n", best_move.x, best_move.y);

    return 0;
}
