五子棋游戏源码，如何优化算法以提升对弈体验？

五子棋游戏源码是一套用于开发 五子棋游戏的计算机程序代码。它通常包括游戏逻辑、界面设计、人工智能（AI）对手等功能模块，使得开发者能够构建出一个可供玩家下棋的互动环境。

import os
import sys
BOARD_SIZE = 15
def print_board(board):
    for row in board:
        print(" ".join(row))
def check_win(board, x, y, player):
    directions = [(1, 1), (1, 0), (1, 1), (0, 1)]
    for dx, dy in directions:
        count = 1
        for i in range(1, 5):
            nx, ny = x + i * dx, y + i * dy
            if 0 <= nx < BOARD_SIZE and 0 <= ny < BOARD_SIZE and board[nx][ny] == player:
                count += 1
            else:
                break
        for i in range(1, 5):
            nx, ny = x  i * dx, y  i * dy
            if 0 <= nx < BOARD_SIZE and 0 <= ny < BOARD_SIZE and board[nx][ny] == player:
                count += 1
            else:
                break
        if count >= 5:
            return True
    return False
def main():
    board = [["." for _ in range(BOARD_SIZE)] for _ in range(BOARD_SIZE)]
    players = ["X", "O"]
    current_player = 0
    while True:
        os.system("clear")
        print_board(board)
        print(f"轮到 {players[current_player]} 下棋")
        x, y = map(int, input("请输入坐标（格式：x y）：").split())
        if board[x][y] != ".":
            print("该位置已有棋子，请重新输入！")
            continue
        board[x][y] = players[current_player]
        if check_win(board, x, y, players[current_player]):
            os.system("clear")
            print_board(board)
            print(f"{players[current_player]} 获胜！")
            break
        current_player = 1  current_player
if __name__ == "__main__":
    main()

这是一个简单的五子棋游戏源码，使用Python编写，游戏棋盘大小为15×15，玩家可以输入坐标来下棋，游戏会检查每次下棋后是否有一方获胜，如果有一方获胜，游戏结束。
