		<description>我对这些数学游戏很着迷，呵呵。这个网站已经在我的收藏夹很久了。

打算开始学习魔方，zeal咱俩来比比:)</description>

		<description>我对soduko一直有看法：我觉得出soduko的人挺无聊的，我宁愿去做crossword。现在是计算机时代了，咱们与其研究具体的题怎么解不如研究怎么建数学模型用计算机解。如果其Logic是线性的，用待定系数列一个整数线性规划模型应该不难解出。题目说Logic是唯一的，那么问题可能最终会归结到某个9x9的矩阵的维度是9的判据上。对于非线性的，则要复杂一些了，不过用合理的assumption加一些函数库挨个试组合，就像用字典破解密码一样，也应该能解出来，理论上应该比人解得快。感觉出soduko的人就是拿个数学模型作为Logic来整人的，设计一个100x100的矩阵只需几秒钟，只要模型是高度非线性的，估计没人能在有生之年猜出答案...</description>
