2.2 基本遗传算法 基本遗传算法(也称标准遗传算法或简单遗传算法，Simple Genetic Algorithm，SGA) 是一 种群体型操作，该操作以群体中的所有个体为对象，只使用基本遗传算子(Genetic Operator)： 选择算子(Selection Operator)、交叉算子(Crossover Operator)和变异算子(Mutation Operator)，其 遗传进化操作过程简单，容易理解，是其它一些遗传算法的基础，它不仅给各种遗传算法提供 了一个基本框架，同时也具有一定的应用价值。选择、交叉和变异是遗传算法 3 个主要操作算 子，它们构成了所谓的遗传操作，使遗传算法具有了其它传统方法没有的特点。 2.2.1 基本遗传算法的数学模型 基本遗传算法可表示为： ),,,,,,,( 0 TΦMPECSGA = (2.1) 式中：C ——个体的编码方法； E ——个体适应度评价函数； 0 P ——初始种群； M ——种群大小； Φ——选择算子； ——交叉算子；  ——变异算子； T ——遗传运算终止条件。 图 2.3 为基本遗传算法的流程图。 2.2.2 基本遗传算法的步骤 1．染色体编码与解码 基本遗传算法使用固定长度的二进制符号串来表示群体中的个体，其等位基因是由二值 {0，1}所组成。初始群体中各个个体的基因可用均匀分布的随机数来生成。例如： X=100111001000101101 就可表示一个个体，该个体的染色体长度是 n=18。 编码和初始种群的生成 种群中个体适应度的检测评估 选择 交叉 变异 图 2.3 遗传算法的基本流程图

This is the fifth edition of a one-of-a-kind engineering reference book covering the past, present, and future of mechanisms and mechanical devices. It includes clear illustrations and straightforward descriptions of specific subjects rather than the theory and mathematics found in most engineering textbooks. You will find that this book contains hundreds of detailed line drawings that will hold your interest regardless of your background in mechanical engineering. The text accompanying the illustrations is intended to help you to understand the basic concepts of subjects that may or may not be familiar to you. You will find drawings and illustrations that are simply interesting and informative and perhaps others that could spur your creativity and prompt you to recycle them into your new designs or redesigns. They may offer solutions you had not previously considered because they were not visible inside contemporary products unless the product is disassembled. Solid state electronics and computer circuitry have displaced many earlier mechanical solutions, no doubt improving product reliability and efficiency while reducing their price. Nevertheless, many of those displaced mechanical components have lives of their own and may very well turn up in other products in different form performing different functions after undergoing dimensional and material transformations. Classical, proven mechanisms and mechanical devices may seem to disappear only to reappear in other forms and applications. Anyone who believes that all mechanisms will be replaced by electronics need only examine the sophistication of the latest self-winding mechanical watches, digital cameras, gyro-stabilized vehicles, and navigational systems. This book illustrates the ongoing importance of classical mechanical devices as well as the latest mechatronic devices formed by the merger between mechanics and electronics. It is a must addition to your personal technical library, and it offers you a satisfy

Electrostatic discharge (ESD) phenomena have been known to mankind since the Greek Empire when Thales of Miletus, one of the Seven Sages of Greece, noticed the attraction of strands of hay to amber, leading to the coining of the word ‘‘electron.’’ In the 17th century, Gilbert and Cabeo addressed the attractive and repulsive nature of electricity. In the 18th century, a rapid increase of interest occurred for scientists in the understanding of electrical physics—Gray, du Fay, Nollet, Musschenbroeck, Franklin, Watson, Aepinus, Canton, Priestley, Cavendish, Galvani, Coulomb, Volta, Poisson, Faraday—and continued into the 19th century—Laplace, Gauss, Oersted, Ampere, Davy, Ohm, Green, Ostrogradsky, Henry, Lord Kelvin, Joule, Neumann, Weber, Thomson, Kirchoff, Stokes, Helmholtz, and Maxwell. It was the discoveries made in the 1820s by Oersted, Ampere, Davy, and Ohm that began the basic understanding of electrical circuits.
