遗传算法从代表问题可能潜在的解集的一个种群开始的，而一个种群则由经过基因编码的一定数目的个体组成。本代码以旅行商问题为例，详细介绍遗传算法的使用方法。(A genetic algorithm the representation of the solution set of potentially the beginning, but after a certain number of the population the gene encoding the individual components. The code to the traveling salesman problem, for example, describes the use of genetic algorithms.)

Study of a DC-DC Converter for Solar LED Street Lighting: Recently, light-emitting diodes (LEDs) are becoming increasingly attractive lighting sources in our daily lives. They are well suited to indoor and outdoor energy-saving lighting applications, such as general lighting, architectural lighting, traffic lighting, background lighting, displays, street lighting, automotive and motorcycle lighting, decorative lighting, and so on. The placement of street lights is closely related to the development of one area or region, and they represent the financial success of a city. For street lighting applications, the traditional lighting sources are high-pressure sodium lamps and high-pressure mercury lamps. Recently, LEDs are commonly being used as new sources for street lighting because of their attractive features of good lighting efficacy, energy-savings, that they are non-polluting to our environment, and that they offer a long lifetime in comparison to their traditional counterparts.

最优分割的基本思路是给定一个数据序列和分层数，通过搜索所有可能的划分方案，找到段内离差平方和的总和最小的一种方案作为最终划分方案。这里给出最优分割法的Matlab源程序(The basic idea is optimal partition for a given data sequence and hierarchical number divided by searching all possible solutions to find the segment and the sum of the squared deviations smallest division of a scheme as a final solution. This gives the optimal segmentation Matlab source)
