说明：  一种核密度估计，或者称作带宽选择的方法，可以估计二维尺度参数，至于多维以上的估计方法尚在开发，多维情况下个人经验好的方法是多次实验取较好值(kernel density estimation, bandwidth selection, two-dimensional scale parameter can be estimated ,for the multi-dimensional approaches are still under development, multi-dimensional cases, personal experience is to do the experiment many times)

说明：  EM算法代码，利用类电磁机制求解优化问题的优化算法可以达到全局最优的算法，并且不要求目标函数可微(EM algorithm code, the use of the electromagnetic mechanism to solve the optimization problem of the optimization algorithm can achieve the global optimal algorithm, and does not require differentiable objective function)

this code is regarding to one simple network area. this code consists of some access points and link between them using distance relation. some access points are far away the signal transmitted

都市供求信息网分为前后台的设计，前台主要实现信息的显示、搜索与发布功能。其中信息的显示包括列表显示与详细内容显示，而列表显示，又分为首页面的信息列表显示、查看某类别下所有信息的列表显示和搜索结果列表显示；搜索功能主要包括定位搜索和模糊搜索；后台主要实现的功能为信息显示、信息审核、信息删除、付费设置与退出登录，其中的信息显示功能也分为列表显示与详细内容显示。(Urban supply and demand information network is divided into front and back design, front main achievement of the displayed information, search and publishing. Which displays information including a list of displays and display details, but the list is displayed, the information is divided into the home side s display list, a list of all the categories of information under the display and view a list of search results display Search functions include positioning search and fuzzy search the main function of the background information display, information auditing, information deleted, pay setting and exit the registry, which is also divided into the information display function displays detailed contents list display.)

根据PSO算法原理，在MATLAB中编程实现基于PSO算法的函数极值寻优算法，程序前面给出了PSO算法参数设置，种群初始化，寻找初始极值，迭代寻优，最后通过算法反复迭代300次，画出每代最优个体适应度值变化曲线，最后通过对比发现说明PSO算法具有较强的函数极值寻有能力，谢谢，希望对大家有帮助。 (According to the principle of PSO algorithm in MATLAB programming function PSO algorithm based on extreme value optimization algorithm, the preceding program gives the PSO algorithm parameter settings, population initialization, looking for initial extreme value, iterative optimization, and finally through the iterative algorithm 300 times draw the best individual fitness value of each generation curve, and finally by comparing the findings indicate that PSO algorithm has strong function extreme ability to find, thank you, we want to help.)
