Description: 优化问题是工业设计中经常遇到的问题,许多问题最后都可以归结为优化问题. 为了解决各种各样的优化问题,人们提出了许多优化算法,比较著名的有爬山法、遗传算法等.优化问题有两个主要问题:一是要求寻找全局最小点,二是要求有较高的收敛速度. 爬山法精度较高,但是易于陷入局部极小. 遗传算法属于进化算法( Evolutionary Algorithms) 的一种,它通过模仿自然界的选择与遗传的机理来寻找最优解. 遗传算法有三个基本算子:选择、交叉和变异. 但是遗传算法的编程实现比较复杂,首先需要对问题进行编码,找到最优解之后还需要对问题进行解码,另外三个算子的实现也有许多参数,如交叉率和变异率,并且这些参数的选择严重影响解的品质,而目前这些参数的选择大部分是依靠经验.1995 年Eberhart 博士和kennedy 博士提出了一种新的算法;粒子群优化(Particle Swarm Optimization -PSO) 算法 . 这种算法以其实现容易、精度高、收敛快等优点引起了学术界的重视,并且在解决实际问题中展示了其优越性。

Description: C 语言中的类模拟（C++编程思想） 在面向对象的语言里面，出现了类的概念。这是编程思想的一种进化。所谓类：是对特定数 据的特定操作的集合体。所以说类包含了两个范畴：数据和操作。而C 语言中的struct 仅仅是数 据的集合。-C language of analog (C Programming thinking), the object-oriented languages inside, a kind of concept. This program is an evolutionary thinking. The so-called categories : data specific to the particular operation of the collectivity. So category contains two areas : data and operation. While the C language struct is just a collection of data.
