python字符型五子棋人工对战

以下是一个简单的 Python 代码，用于实现两个人工智能之间的五子棋对战。其中，每个人工智能都会根据当前棋盘状态进行决策，并在棋盘上放置自己的棋子，直到有一方获胜或者棋盘被下满。

import numpy as np

# 初始化棋盘
def init_board():
    board = np.zeros((15, 15))
    return board

# 判断当前位置是否可以下棋子
def is_valid_move(board, row, col):
    return board[row][col] == 0

# 判断是否有一方获胜
def is_win(board, player):
    for i in range(15):
        for j in range(11):
            if board[i][j] == player and board[i][j+1] == player and board[i][j+2] == player and board[i][j+3] == player and board[i][j+4] == player:
                return True
    for i in range(11):
        for j in range(15):
            if board[i][j] == player and board[i+1][j] == player and board[i+2][j] == player and board[i+3][j] == player and board[i+4][j] == player:
                return True
    for i in range(11):
        for j in range(11):
            if board[i][j] == player and board[i+1][j+1] == player and board[i+2][j+2] == player and board[i+3][j+3] == player and board[i+4][j+4] == player:
                return True
    for i in range(11):
        for j in range(4, 15):
            if board[i][j] == player and board[i+1][j-1] == player and board[i+2][j-2] == player and board[i+3][j-3] == player and board[i+4][j-4] == player:
                return True
    return False

# 判断是否有一方胜利
def game_over(board):
    if is_win(board, 1) or is_win(board, 2):
        return True
    if len(np.where(board == 0)[0]) == 0:
        return True
    return False

# 人工智能下棋
def ai_move(board, player):
    for i in range(15):
        for j in range(15):
            if is_valid_move(board, i, j):
                board[i][j] = player
                if is_win(board, player):
                    return
                board[i][j] = 0

# 人工智能对战
def play():
    board = init_board()
    player = 1
    while not game_over(board):
        if player == 1:
            row = int(input("Player 1, Enter row: "))
            col = int(input("Player 1, Enter col: "))
            if is_valid_move(board, row, col):
                board[row][col] = player
            else:
                print("Invalid move, try again.")
                continue
        else:
            ai_move(board, player)
        print(f"Current board:\n{board}")
        player = 3 - player
    if is_win(board, 1):
        print("Player 1 wins!")
    elif is_win(board, 2):
        print("Player 2 wins!")
    else:
        print("Tie game.")

# 开始游戏
if __name__ == "__main__":
    play()

这个程序中，我们使用了一个 15x15 的 numpy 数组表示棋盘，为了方便，在每个位置上，0 表示空位，1 表示玩家1，2 表示玩家2。我们通过 is_valid_move 函数来判断一个位置是否可以下棋子，通过 is_win 函数来判断是否有一方获胜。在 ai_move 函数中，我们使用了简单的枚举方式来实现人工智能的决策。最后，我们通过 play 函数来初始化游戏并进行对战。
