最小二乘法圆拟合，用于图像处理，比较复杂，请耐心看完，也可直接使用-least square error (LSE) circle fitting, applicable to image processing, a little complicated, can be used directly

OFELI is an object oriented library of C++ classes for development of finite element codes. Its main features are : * Various storage schemes of matrices (dense, sparse, skyline). * Direct methods of solution of linear systems of equations as well as various combinations of iterative solvers and preconditioners. * Shape functions of most "popular" finite elements * Element arrays of most popular problems (Heat Transfer, Fluid Flow, Solid Mechanics, Electromagnetics, ...).-OFELI is an object oriented library of C++ classes for development of finite element codes.

用Kruskal算法构造最小生成树解决指派问题（assignment problem） 一家公司经理准备安排 名员工去完成 项任务，每人一项。由于各员工的特点不同，不同的员工去完成同一项任务时所获得的回报是不同的。如何分配工作方案可以使总回报最大？ -Kruskal Algorithm used to solve assignment problem minimum spanning tree (assignment problem), a manager of the company prepare arrangements for employees to complete tasks, each one. As a result of the characteristics of different staff, different staff to accomplish the same mission when the return is different. How to allocate the work program can make the greatest total return?

VB源程序,层次分析算法.可以解决系统模糊评价的问题. 本算法结构清晰,适宜定量评价系统性能-VB source, the level of analysis algorithm. Fuzzy system can solve the problem of evaluation. This algorithm clear and suitable for quantitative evaluation of system performance

操作系统中的同步于互斥问题一直是一个难题，相对与独木桥问题而言，中间可以过两个人而两边只可以一次过一个人的问题，要更为复杂，如何让同步程度更大去实现该算法也更为不易。

k-d树 （k-dimensional树的简称），是一种分割k维数据空间的数据结构。主要应用于多维空间关键数据的搜索（如：范围搜索和最近邻搜索）。K-D树是二进制空间分割树的特殊的情况。ICP算法最初由Besl和Mckey提出，是一种基于轮廓特征的点配准方法。基准点在CT图像坐标系及世界坐标系下的坐标点集P = {Pi, i = 0,1, 2,…,k}及U = {Ui,i=0,1,2,…,n}。其中，U与P元素间不必存在一一对应关系，元素数目亦不必相同，设k ≥ n。配准过程就是求取 2 个坐标系间的旋转和平移变换矩阵，使得来自U与P的同源点间距离最小

WMI(Windows®Management Instrumentation ) 非常强大，它可以以数据库的形式查询你的电脑的软件和硬件，在它的数据库里面，时刻保存着最新的软件信息和硬件信息，因此你可以用WMI来检测CUP 主频、温度，读取WINDOWS的进程......... 本文就介绍如何使用WMI读取USB设备的PID和VID码
