Description: 模拟退火算法来源于固体退火原理，将固体加温至充分高，再让其徐徐冷却，加温时，固体内部粒子随温升变为无序状，内能增大，而徐徐冷却时粒子渐趋有序，在每个温度都达到平衡态，最后在常温时达到基态，内能减为最小。根据Metropolis准则，粒子在温度T时趋于平衡的概率为e-ΔE/(kT)，其中E为温度T时的内能，ΔE为其改变量，k为Boltzmann常数。用固体退火模拟组合优化问题，将内能E模拟为目标函数值f，温度T演化成控制参数t，即得到解组合优化问题的模拟退火算法：由初始解i和控制参数初值t开始，对当前解重复“产生新解→计算目标函数差→接受或舍弃”的迭代，并逐步衰减t值，算法终止时的当前解即为所得近似最优解，这是基于蒙特卡罗迭代求解法的一种启发式随机搜索过程。退火过程由冷却进度表(Cooling Schedule)控制，包括控制参数的初值t及其衰减因子Δt、每个t值时的迭代次数L和停止条件S。

Description: 看了袁渊先生在VC知识库《在线杂志》第14期发表的文章《基于TCP/IP的局域网多用户通信》，感觉受益颇多，但也觉得里面有一些不太完善的地方，具体来说主要有：
1、两个服务器单独运行，且主线程均阻塞，用户界面死锁，不便于控制；
2、聊天服务器线程和互斥量的使用可能导致死锁；
3、不能实现文件传送（文件传送可不能由服务器转发，否则非把它累趴下不可^-^）；
4、不能由用户进行网络设置，所以在不同的网络使用必须修改源程序等等；
我在此基础上重新设计编写了一个系统
-read YUAN Yuan in VC knowledge base "online magazine" 14 published an article, "based on TCP/IP LAN multi-user communication", I feel a lot of benefit, but also think that there are some less than perfect, specifically are : 1, 2 server running, and the main threads are blocked, the user interface Deadlock, facilitate control; 2, chat server threads and contradict the use of volume may lead to deadlock; 3, achieve file transfer (FTP can be transmitted by the server, otherwise he will not get on the ground tired ^- ^) ; 4, and not by users for network configuration, the different networks must be revised source, etc.; I would like to re-design on the basis of the preparation of a system
