说明：  相关优化算法的MATLAB程序,本程序为粒子算法的程序。共有13个程序。(Related to the MATLAB optimization procedure, the procedure for the particle algorithm process. A total of 13 procedures.)

说明：  Objects forming possible solution within original problem context are called phenotypes, their encoding, the individuals within the GA, are called genotypes. The representation step specifies the mapping the phenotypes onto a set of genotypes. Candidate solution, phenotype and individual are used to denotes points of the space of possible solutions. This space is called phenotype space. Chromosome, and individual can be used for points in the genotye space. Elements of a chromosome are called genes. A value of a gene is called an allele. Variation Operators The role of variation operators is to create new individuals old ones. Variation operators form the implementation of the elementary steps with the search space.

循环冗余校验CRC (Cyclic Redundancy Check)码是由分组线性码的分支而来，其主要应用是二元码字。编码简单且误判概率很低，在通信系统中得到了广泛的应用。循环冗余校验码是属于分组码中的一类重要的线性码，它不仅在理论上具有很好的代数结构，而且其编码和译码可以通过线性移位寄存器很容易地实现。 通过对CRC的分析和基于MATLAB工具的仿真，充分证明了CRC的检错能力很强，编码简单。 (Cyclic Redundancy Check CRC (Cyclic Redundancy Check) code is a linear code from the sub-branch from the main application is the binary code word. Coding is simple and very low probability of miscarriage of justice, in the communication system has been widely used. Cyclic redundancy check code is a block code in one important class of linear code, which not only has good in theory, algebraic structure, and its encoding and decoding of linear shift register can easily realize . CRC through analysis and simulation tool based on MATLAB, and fully proves that the CRC error detection ability of a strong, simple coding.)
