为什么叫“单纯形“?这个名字有什么意义 - 知乎
单纯形 是二维的三角形,三维的四面体,在任意维度的推广。n-维单纯形是一个有 n+1 个顶点,n+1 个面 (facet) 的多面体。这个词译自英语 simplex,「单纯」其实意味着基本,因为他是组成更复杂结构(复形 complex)的基本构件。( Simplex ) 线性规划 中的 单纯形法,似乎与单纯形没有很大关系。但是 ...

我在3dm下了个游戏 下完是一堆压缩包,怎么样才能合成游戏 我各种解压 也没有exe的文件,? - 知乎
游戏是分卷压缩的,找到标号(文件后缀)最开始的的那个压缩包(有些压缩软件会自动判定哪个是卷首,所以随便选个压缩包就行),右键解压,解压完成后,3dm的里面一般还会再有一个文件夹和几个小广告,点进文件夹,里面有exe文件,运行即可。

线性规划问题的复杂度为多少? - 知乎
如果使用的是 单纯形法 (simplex)的话,是指数级复杂度,因为worst case是需要遍历所有顶点来找到最优解。 如果使用的是 内点法 (interior point method)的话,是多项式复杂度。 复杂度为O (n^3.5 L),其中n为变量的个数,L为问题编码的bits位数。 参考资料:
