第一次写博客，想总结分享下以前做过的一些有趣的东西，目的是为了回望过去与展望未来，同时为了提高自己的写作表达能力。
思路与步骤
- 三阶魔方有6个面，每个面有 3 × 3 3\times3 3×3小块，用一个 6 × 3 × 3 6\times3\times3 6×3×3的矩阵来保存魔方的状态；
- 定义4+12种魔方旋转行为：整体旋转（左右上下共4种方式AaCc），侧面（6个侧面顺逆时针旋转共12种方式LlRrUuDdFfBb），旋转可视化界面方便调试（三维小面作图fill3创建 6 × 3 × 3 = 54 6\times3\times3=54 6×3×3=54个小面对象，对象成员属性包括颜色和4个三维坐标点，定义了全局函数对小面进行绕轴旋转操作，如此可以可视化调试，确保程序是按人想法运行），旋转行为改变矩阵的状态矩阵；
- 定义随机打乱和逆序恢复的函数，测试确保人为给出旋转公式，魔方能正确旋转；
- 编写按公式恢复魔方的函数，记录恢复过程的旋转过程公式（取一个魔方一边拧一边编程，考虑所有情况）
1)：顶层拼十字：简化为4次恢复顶面棱中小块（不破坏已恢复的结果）
2)：顶层拼四角：简化为4次恢复顶面的角小块（不破坏已恢复的结果）
第一层恢复完成，剩下可按公式恢复魔方，把第一层置底
3)：二层拼棱角：简化为4次恢复二层棱角小块（不破坏已恢复的结果）
第二层恢复完成
4)：按公式顶层拼十字
5)：按公式顶层四角对应恢复
6)：按公式顶面同色恢复
7)：按公式顶面棱边恢复
第三层恢复完成 - 编写一个公式简化的函数，如消除相邻正反操作、消除4次相同操作、3次同向旋转替换为一次反向旋转操作、不相关跳跃旋转整合等，未能考虑所有可化简的情况，还未能化简为最少旋转步数公式。时间精力有限，待以后有新思路的时候再玩。
总结
很多指令都是现查现用的，编程模块化，过程分解，编程周期较长，编完以后，整体思路清晰，但单独模块缺少注释，不好看懂，特别是手动旋转对应编程部分，时间久了容易忘记。这是2019年1月编的代码（忘记了具体参考过哪些代码了），现在整理下思路，这里三阶魔方恢复算法是普通的按公式还原算法，主要难点在于判断魔方的状态，我编程的过程中是实际拿着个魔方一边转一边进行状态观察遍历，方法比较笨，可以实现自动魔方还原，但是还原步骤较多，程序中通过增加一些函数进行了步骤的简化
function TurnManu=simplifyTurnManu(TurnManu)
但是简化结果并不彻底，需要更高级的简化函数，或高级的魔方恢复算法。
思考
如果能够用快速相机记录并识别魔方高手旋转魔方的方法，通过机器学习、聚类、迁移等思想，改善算法，数据即算法？如果没有如果，给定初始的算法，能不能让算法自己通过运行自学习，更新算法，或者产生模拟高级的数据用于机器学习？感觉这会不会是一个很好的案例？数据为王？算法为王？Alpha Zero从0开始？有人实现了吗？
