关键优化说明
-
多难度级别配置：
- 简单（1秒/2000次模拟）：适合初学者
- 中等（3秒/8000次模拟）：业余3-4段水平
- 困难（10秒/20000次模拟）：业余5段以上水平
-
性能优化技术：
- 动态调整思考时间与模拟次数平衡
- 优先搜索已有棋子周围的区域
- 添加简单启发式规则加速模拟阶段
-
用户体验改进：
- 显示AI思考时间和模拟次数
- 添加坐标系统方便定位
- 最后一步落子标记
- 悔棋功能
-
自适应策略：
- 模拟过程中10%概率使用启发式规则
- 自动检测关键胜负手（四连阻断等）
使用说明
- 选择难度级别（简单/中等/困难）
- 黑棋先行，点击棋盘落子
- AI会自动计算并回应
- 可使用"悔棋"按钮撤销上一步
- 游戏结束时会显示胜负结果
这个实现通过精心调参和优化资源分配，在保持算法核心不变的情况下，显著提升了AI强度。困难模式下的AI已经能够达到业余高段位水平。
