华为GTM900AT命令手册，对开发GPRS具有指导意义(Huawei GTM900 AT command manual，It has a guiding significance to develop GPRS )

web版微信协议分析。当前分析到登陆部分。举一反三，后续的拉取好友列表和发送消息等协议都好分析出来了。作者：孙强壮。(The web version of the micro-channel protocol analysis. Current analysis to the landing part. Giving top priority to, the subsequent pull friends list and send messages agreements out a good analysis.)

随着网络带宽的越来越大以及嵌入式技术和嵌入式设备的日益发展成熟，过去的很 多设备如今变成了可管理的网络设备，它们不仅嵌入了操作系统和拥有自己的IP 地址，而 且还通过嵌入web 形式的网络代理端以方便用户的控制和管理。本文通过在arm920t 的开发 板上移植BOA（一个开源的web server），并嵌入到接入网络设备当中以实现对其进行web 化的控制和管理。(With increasing network bandwidth and embedded technology and the increasing development of sophisticated embedded devices, over the past many devices now become manageable network equipment, which not only embedded operating system and has its own IP address, and through web forms embedded in the network proxy client to facilitate the user' s control and management. In this paper, the development board in arm920t transplant BOA (an open source web server), and embedded in the access network equipment for them to achieve their web based control and management.)

不错的客户端连接程序，希望大家喜欢，里面是一个客户端的程序，一会会提供服务端的程序(good client procedures in the hope that everyone likes, there is a client process, will provide a service side of the process)

说明：  求解双层规划问题常用的算法有极点算法、直接搜索法、下降法和非数值优化方法(如模拟退火算法、遗传算法等)，遗传算法的求解思路是：首先对上层的决策变量编码，代人下层规划模型，通过求解下层模型的决策变量值，代入上层模型计算适应度值，然后进行交叉、变异、选择操作，最后求出最优解。(Solving Bilevel Programming Problems with pole algorithm commonly used algorithms, direct search method, descent and non-numerical optimization methods (such as simulated annealing, genetic algorithms, etc.), genetic algorithm for solving approaches: the first on the top of the decision variable coding, on behalf of the were lower programming model, by solving the lower model of decision variables values into the upper model on behalf of the fitness value, and then crossover and mutation, select Options, and finally get the best solution.)
