EXCEL formula to introduce the main functions, such as FIND, SEARCH

1算法思路  K-means算法  先随机选取K个对象作为初始的聚类中心。然后计算每个对象与各个种子聚类中心之间的距离，把每个对象分配给距离它最近的聚类中心。聚类中心以及分配给它们的对象就代表一个聚类。一旦全部对象都被分配了，每个聚类的聚类中心会根据聚类中现有的对象被重新计算。这个过程将不断重复直到满足某个终止条件。终止条件可以是以下任何一个：  1)没有（或最小数目）对象被重新分配给不同的聚类。  2)没有（或最小数目）聚类中心再发生变化。  3)误差平方和局部最小。  2算法步骤 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

C语言程序，模拟UNIX磁盘空间管理中使用的分组链接法。程序内有主要要求-a C program ,it simulates the method of space management grouping links in the unix disk space management.

模拟固定分区存储管理的分配与回收。固定分区就是把内存区固定地划分为若干个大小不等的区域。分区一旦划分结束，在整个执行过程中每个分区的长度和内存的总分区个数将保持不变。当用户进程提出内存分配要求时，找到满足要求的分区分给它，进程执行完后，回收进程和它占有的资源-Simulation regular distribution and recovery which stores management of dividing into area. The regular assigning to area divides the memory district into several areas not of uniform size regularly. Divide and is over in the dividing area, the number of total points area of the length and memory of the each one area will keep intact in the whole course of carrying out. When user s process proposes the demand of assigning of the memory , find fen meeting the demands to distinguish to it, after the process is carried out, retrieve the process and resource which it occupy

我在一个英文网站上找到的C程序，实现了著名的“贪食蛇”游戏。程序中的图形完全采用文字画的形式，很有特色。我曾经和作者用电子邮件联系过，此程序可以任意传播。-in an English website to find the C program, realized the famous "Snake" game. The procedures are used graphic language in the form of paintings, very unique. I had e-mail contact with the author that this procedure can be arbitrary spread.
