您提供的 `get_neighbors` 函数代码不完整,存在以下问题:
- 缺少 `def` 关键字(开头是 `ef`)
- `dirs` 和 `res` 赋值未完成
- `for` 循环缩进错误
- `if` 条件未闭合
- 缺少 `return` 语句
以下是修正后的正确函数(以 19 路棋盘为例),可直接使用:
-
- def get_neighbors(r, c):
- dirs = [(-1,0), (1,0), (0,-1), (0,1)]
- res = []
- for dr, dc in dirs:
- nr, nc = r + dr, c + dc
- if 0 <= nr < SIZE and 0 <= nc < SIZE:
- res.append((nr, nc))
- return res
复制代码
您需要确保在函数外定义了 `SIZE`(例如 `SIZE = 19`)。
如果希望直接运行完整的人机对战程序,请参考之前提供的新代码(已修正所有语法错误)。请将以下完整代码复制到 Python 文件中运行(建议使用 9 路棋盘测试,速度更快):
-
- import tkinter as tk
- import random
- SIZE = 9 # 可改为 19
- def init_board():
- return [[0]*SIZE for _ in range(SIZE)]
- def get_neighbors(r, c):
- dirs = [(-1,0),(1,0),(0,-1),(0,1)]
- res = []
- for dr, dc in dirs:
- nr, nc = r+dr, c+dc
- if 0 <= nr < SIZE and 0 <= nc < SIZE:
- res.append((nr,nc))
- return res
- def get_group(board, r, c, color):
- stack = [(r,c)]
- visited = {(r,c)}
- group = []
- while stack:

将以上代码另存为 `go_human_vs_ai.py` 运行即可。AI 会执与您当前颜色相反的颜色(即您执黑时 AI 执白,您按2切换白时 AI 执黑)。通过按键盘 1 或 2 可主动切换当前落子颜色。
您还可以通过修改 `SIZE` 为 19 来使用标准棋盘(但 AI 运算会变慢)。提升 AI 强度可改进 `evaluate_move` 中的评分函数(例如加入围地面积、眼位等因素)。
