这是一个简单的算法来跟踪太阳位置和摄像机的云。太阳位置估计是由圆拟合和云是分类容易门限方案。这个源代码是为类项目实现的。谢谢你。

FPgrowth is the one of the algorithm in frequent item set mining. It is used to find the frequent item set in a database. It will give the output in tree structure format. It is more efficient than apriori algorithm because there is no candidate generation. 

大M单纯形线性规划问题求解。 很不错的基于basic的源代码啊-Large M simplex linear programming problem solving. Very good basic source code based on ah

本算法为哈弗曼编码，主要为手动输入一个字符串，自动统计字符种类和权值，进行哈弗曼编码。要译码的话输入二进制代码，进行译码...

此小程序可以根据IP地址，查询到它的机器的归属地！-This small program can be the basis of IP addresses, inquiries to its attribution to the machine!

98年全国大学生数学建模竞赛B题“水灾巡视问题”，是一个推销员问题，本题有53个点，所有可能性大约为exp(53),目前没有好方法求出精确解，既然求不出精确解，我们使用模拟退火法求出一个较优解,将所有结点编号为1到53,1到53的排列就是系统的结构,结构的变化规则是:从1到53的排列中随机选取一个子排列,将其反转或将其移至另一处,能量E自然是路径总长度。具体算法描述如下：步1： 设定初始温度T，给定一个初始的巡视路线。步2 ：步3 --8循环K次步3：步 4--7循环M次步4：随机选择路线的一段步5：随机确定将选定的路线反转或移动，即两种调整方式：反转、移动。步6：计算代价D，即调整前后的总路程的长度之差步7：按照如下规则确定是否做调整：如果D0,则按照EXP(-D/T)的概率进行调整步8:T*0.9-->T,降温-98 National Mathematical Contest in Modeling B and that the "flood inspections", is a salesman problem, and that is 53 points, all possibilities about exp (53), there is no good way to get accurate solutions, since no exact solution for, we used simulated annealing France obtained an optimum solution to all nodes to a number of 53 to 53.1 is with the system structure, changes in the structure of the rules is : from 1-53 with a randomly selected with a son, to reverse or to move it to another, the energy E is the natural path length. The specific algorithm is described as follows : Step 1 : The initial set temperature T,

这是一套由剑桥大学出版的一套c语言的科学计算资料及相关的算法源程序，非常权威，这套资料对从事软件开发，科研计算等人都非常有帮助-This is a publication by the University of Cambridge, a set of c language information and related scientific computing algorithm source code, very authoritative, this information is engaged in software development, scientific computing, such as people are very helpful

这是最小二乘法，比较实用，目前俺手中最小二乘法库中的一个，可以用于代码，如果你需要，可以下载，直接搬过去用。-This is the least square method, more practical, I present the hands of the least square method, a library, can be used to code, if you want, you can download directly moved by the past.

能够完成对于MP3 等文件的信息，音频信号进行采集与输出 例如：文件头的歌曲名、歌手等 由于MP3是二进制文件，因此主要根据断点来进行编码实行
