To overcome the premature of simple genetic algorithm, the calculating efficiency of SGA is improved by the following two ways; Firstly, in order to ensure convergence of algorithm and reduce influence factor of convergence, elitist selection and adapted crossover and mutation operator are adopted. Secondly, because this study deals with finding minimize volume of structure, to quicken convergence of this problem, in line with mechanics criterion the paper carry out mutation to some genes in chromosome according to variations of internal force. This will let algorithms to search answer with our hoping directions.

针对基本遗传算法存在早熟的问题，本文主要从两个方面进行了改进，首先为了保证算法的收敛和减少影响算法收敛因素，采用了最优保护策略和自适应的交叉和变异算子；其次，由于本文研究内容涉及求结构最小体积问题，为了加快此类问题的收敛速度，本文结合结构优化中的力学准则，对个体染色体中的某一段基因按照内力变化进行变异操作，使得算法按一定方向进行搜索最优解。

The author also brings his proposal about how to perfect the legislation of common bribery. He suggests: Firstly, in the general principles of criminal law, it should be prescribed definitely no matter the person who has identity or not committing a crime together which is constituted for their identity, the action belongs to common crime. Secondly, in separate principles of criminal law, the spirit of rule about the common bribery crime in "The conversazione summary of country court cognizance economy crime cases" put out by the supreme court of people in 2003 as well as "The notions of some questions about the suitable laws of transacting the bribery case in the supreme court of people and the supreme procurator of people" in 2007 should be put in the separate principles.

对如何完善共同受贿立法作者提出了自己的建议：建议在刑法总则中明确规定，无身份犯与身份犯勾结，共同实施因犯罪人身份而构成的犯罪，属共同犯罪，在分则中把2003年最高人民法院《全国法院审理经济犯罪案件工作座谈会纪要》以及2007年《最高人民法院最高人民检察院关于办理受贿刑事案件适用法律若干问题的意见》关于受贿罪共犯的规定精神纳入，分则中385条可以增加两款：与国家工作人员勾结伙同受贿的，以受贿论处。

In this thesis, we firstly introduce several class of discrete-time neural network models and the research progress of the neural networks. By Schauder fixed-point principle we prove the existence of an equilibrium (i.e. a fixed point) of a discrete-time neural network with generalized input-output function and by using the converse theorem of Lyapunov function we study the uniformly asymptotical stability of equilibrium in this discrete-time neural network with variable weight and give some sufficient conditions that guarantee the stability of it.
