说明：  图论模型及方法 搞计算机算法和数学建模的人都知道图论是一个很重要的内容。本资料介绍了图论中的最短路算法、匹配、邮递员和货郎问题、最小生成树、网络流等经典问题。而且有非常经典易懂的Matlab程序。(Graph theory and methodology of engaging in computer algorithms and mathematical modeling of the people know that graph theory is a very important content. The information presented in graph theory the most short-circuit algorithm, matching, and saleman & postman problem, minimum spanning tree, network flow problem, such as the classic. Has a very classic and easy-to-understand Matlab　programme .)

流形学习，局部线性嵌入式算法(LLE)，一种智能的算法去推测捕捉高维空间中所包含的低维特征。与适合于局部维数约减的聚类算法不同，LLE算法在单一的低维的全域坐标系统中表征采样空间，然而它并没有优化最小局域。通过对线性重构的局域对称的研究应用，LLE能够描述非线性流形的全局结构，例如那些人脸的数据集或者文本文档集(Manifold learning, embedded local linear algorithm (LLE), an intelligent algorithm to predict capture high-dimensional space contained in the low-dimensional features. And for local dimensionality reduction of the different clustering algorithms, LLE algorithm in a single low-dimensional characterization of the global coordinate system, the sampling space, but it does not optimize the local minimum. Reconstructed by the local symmetry of the linear study of the application, LLE can describe the global structure of nonlinear manifolds, such as those who face data sets or text document collection)
