偏最小二乘回归的通用程序，以“基于近红外光谱分析的汽油组分建模”为例 (Partial least squares regression of the general program of " Near infrared spectroscopy based gasoline component modeling" as an example)

运筹学基础教材，很难得的运筹学教材，供大家学习之用。

频谱分析,用于对等时间间距的序列进行频谱分析 很好的(Spectrum analysis for equivalent time interval sequence spectrum analysis is very good)

这是一个数组练习，程序的作用是查询一个一维数组（数值型数组）中每一个元素出现的次数，且元素出现的顺序不能改变(This is an array of exercises, the program' s role is to query a one-dimensional array (numeric array) in the number of occurrences of each element, and the element can not be changed in order of appearance)

指派问题的匈牙利解法，从文件中读入待指派的数据。(Assignment problem of the Hungarian method, read from a file to be assigned to data.)

说明：  上数据挖掘课的课件，是EM算法的，其中还包括最大似然值，最大似然估计，以及cluster(data mining,EM Algorithm ,Likelihood, Mixture Models and Clustering )

BESO的python程序，对于进行abaqus的二次开发很有帮助，这样可以将有限元单独在abaqus中进行处理，而优化算法则采用python进行编写(BESO python program, for the secondary development abaqus helpful, so that the finite element can be handled separately in abaqus, while the optimization algorithm is written in python)
