聚类算法，不是分类算法。分类算法是给一个数据，然后判断这个数据属于已分好的类中的具体哪一类。聚类算法是给一大堆原始数据，然后通过算法将其中具有相似特征的数据聚为一类。这里的k-means聚类，是事先给出原始数据所含的类数，然后将含有相似特征的数据聚为一个类中。所有资料中还是Andrew Ng介绍的明白。首先给出原始数据{x1,x2,...,xn}，这些数据没有被标记的。初始化k个随机数据u1,u2,...,uk。这些xn和uk都是向量。根据下面两个公式迭代就能求出最终所有的u,这些u就是最终所有类的中心位置。(Clustering algorithm, not a classification algorithm. Classification algorithm is to give a figure, and then determine the data belonging to a specific class of good which category. Clustering algorithm is to give a lot of raw data, and then through the algorithm which has similar characteristics data together as a class. Here k-means clustering, is given in advance the number of classes contained in the raw data, then the data contain similar characteristics together as a class. All information presented in or Andrew Ng understand. Firstly, raw data {x1, x2, ..., xn}, the data is not labeled. K random initialization data u1, u2, ..., uk. These are the vectors xn and uk. According to the following two formulas can be obtained final iteration all u, u is the ultimate all these classes the center position.)

VPRTW
时间窗物流配送车辆路径问题(Vehicle Routing Prob-
lem ,VRP)最早是由Dantzig 和 Ramser 于 1959 年首次
提出的.该问题的研究目标是 ,对一系列的顾客需求点
设计适当的路线 ,使车辆有序地通过,在满足一定的约
束条件(如货物需求量、发送量 、交发货时间、车辆容量
限制 、行驶里程限制 、时间限制等)下,达到一定的优化
目标(如里程最短、费用最少、时间尽量少、车队规模尽
量小 、车辆利用率高等).(With the development of diversified demand, the time demand of customers
becomes more and more important in logistics distribution. Obviously, lowering
distribution cost, distributing goods timely, improving the service quality, optimizing
logistics distribution vehicle routing problem with Time Windows (VRPTW) is
exigent to corporations.)
