On the basis of analyze of the traditional genetic algorithm and simulated annealing algorithm , the simulated annealing algorithm is imported into the culling strategy and the subsistence strategy of genetic algorithm . by using simulated annealing algorithm to mitigate the stress of culling in genetic algorithm and utilizing the boltzmann mechanism of simulated annealing algorithm to control the acceptance of the individuals generated by copulated and varied , a cdma multi - user detection method based on simulated annealing genetic algorithm is proposed . genetic algorithm is suited to numeric solution of multi - variance and has good compatibility 在分析传统遗传算法、模拟退火算法的基础上，将模拟退火算法引入遗传算法的选择策略和生存策略，通过模拟退火算法来减轻遗传算法的选择压力，利用模拟退火算法的boltzman机制来控制接收交叉和变异后的个体，针对多用户检测问题的特点，提出了一种“基于模拟退火遗传算法的cdma多用户检测方法” 。
When solving independent problems , the mathematical analysis shows that when a schema whose fitness is higher than the overall average fitness , the schema ' s exponential increase index of trials allocated in the next generations of coevolutionary genetic algorithm ( cga ) is higher than that of csga 数学分析表明，对于独立多问题，共同进化算法采用按比例选择策略时，高于平均适应值的模式的逐代递增指数高于传统单种群遗传算法，说明共同进化算法的效率高于传统的单种群遗传算法。
The article also makes a comprehensive evolution about the brand traits of famous international cosmetics as well as their marketing strategies and gives suggestions for domestic enterprises to improve their marketing . it also put forward the following points for solving the problems : ( 1 ) making full use of self - superiority and having a clear understanding about self - resources ; ( 2 ) making correct competition position . regional market choosing and market segmentation are crucial for taking market opportunities ; ( 3 ) choosing right orientation for the r & d ; ( 4 ) making objective and timely self - evolution ; ( 5 ) the manager of cosmetics enterprises must change the old sense and have a right viewpoint and fairly good capabilities , implementing scientific human resources management and establishing enterprise culture ; ( 6 ) implementing marketing and brand management 本文对世界名牌化妆品及其营销状况进行了综合分析评价，总结出提高我国化妆品营销水平的途径： ( 1 )国内化妆品企业应发挥自身优势，正确认识自身资源； ( 2 )正确确定企业的竞争定位，明确界定企业的进入领域，实施市场细分和区域市场选择策略，并以此获得市场机会； ( 3 )以科学的态度开发产品，树立正确的产品研发方向； ( 4 )正确、及时地评估自己； ( 5 )化妆品企业经营者应改变经营观念并具备较高的素质，对企业进行科学的人力资源管理和企业文化建设； ( 6 )实施正确的营销管理和品牌管理策略。
This article firstly has proven that the core of enterprise goals is the value creation maximization based on stakeholder benefits . in order to achieve this goal , the enterprise must start with enterprise ' s value fountainhead ( customer ' s demand ) and choose the strategy to meet customer ' s demands high - efficiently 本文首先论证了企业目标的核心是兼顾利益相关者利益的价值创造最大化，为了实现这一目标，就必须从企业的价值源泉(顾客的需求)入手，选择策略来高效的满足顾客的需求。
