PCA技术的一大好处是对数据进行降维的处理。我们可以对新求出的“主元”向量的重要性进行排序，根据需要取前面最重要的部分，将后面的维数省去，可以达到降维从而简化模型或是对数据进行压缩的效果。同时最大程度的保持了原有数据的信息。 (A major advantage of PCA technology is reduce the dimension of the data processing. We can calculate the new " principal component" vector order of importance, according to need to take the most important part of the front, eliminating the rear of the dimensions, dimension reduction can be achieved to simplify the model or the effect of data compression . At the same time maintaining the greatest degree of the original data.)

现今社会网络越来越普及，网购已成为一种常见的消费方式，随之物流行业也渐渐兴盛，每个送货员需要以最快的速度及时将货物送达，而且他们往往一人送多个地方，请设计方案使其耗时最少。 这是数学建模是非常有意思的一个题，本程序用哈密尔顿算法计算(Today more and more popular social networks, online shopping has become a common way of consumption, with the attendant logistics industry has gradually flourished, each delivery person needs to be the fastest speed in time of goods delivery, and they sent the more often a a place, please design it for at least time-consuming. This is the mathematical modeling is a very interesting question, the program algorithm with the Hamilton)
