著名图论问题之一。邮递员从邮局出发送信，要求对辖区内每条街，都至少通过一次，再回邮局。在此条件下，怎样选择一条最短路线?此问题由中国数学家管梅谷于1960年首先研究并给出算法，故名。-Well-known graph theory problems. Postman deliver a letter from the post office proceed to require every street within the right area, at least through the time, return to post office. Under these conditions, how to select a shortest route? This issue by the Chinese mathematician Mei Gu tube study in 1960, and gives the first algorithm, hence the name.

　提出一种改进的禁忌搜索算法来求解背包问题。该算法基于禁忌搜索技术,并采用I&D策略,同时设计了两种针对局 部最优解的变异算子。改进后的算法能有效地弥补标准禁忌算法对初始解依赖的缺陷,同时也避免了搜索停滞的现象。通过对具 体实例和随机问题的测试,表明改进后的禁忌搜索算法有更好的性能。 关-An improved tabu search algorithm to solve knapsack problem. The algorithm is based on tabu search techniques, using I & D strategies, while designed for the local optimal solution of the two kinds of mutation operator. The improved algorithm can effectively compensate for the standard tabu search algorithm depends on the initial solution defect, but also to avoid the phenomenon of search stagnation. Through specific examples and random-question test, indicating that the improved tabu search algorithm has better performance. Guan

RC4算法的Asm实现，实现效率高，可以很方便的用到工程中去-Asm achieve RC4 algorithm to achieve high efficiency, can be very easy to use project to

Base64 编解码演示程序 -Base64 codec demo program

网络验证全套源码，需要ASP空间，具备一定防破解功能，vip源码现在免费使用。 注意：CCasp网络验证3.0 版本的程序附带的几个防御破解功能 并不是就一定能100 防御得到, 只是仅仅提供防御现在大部分破解的手段而已. 因为我个人反破解技术几乎是没多少的,大家也看到那些大型公司.如：腾讯 盛大 等网游公司 他们所运营的游戏当中也有反外挂等程序.程序都有加密什么的.但是还是让各大黑客们芬芬破解掉或者跳过验证等. 我个人并不认为我技术比得上他们这些公司人员的技术. 所以我写的东西还会有被破解的请大家原谅.因为这个不是我个人本身问题. 破解已经是存在了很多年的东西了.而我做的只能给大家防御一下而已... 后台方面的大家不要怕被入侵了.因为我给每个人的都不一样.而且3.0也不是开源的. 希望大家能安心的用就好了. (Network authentication full source code, you need to ASP space, with some anti-crack function, vip source is now free to use.)

利用散列哈希函数对信息进行散列，产生一个定长的信息摘要，从而可实现消息的认证和完整性验证(Hash function is used to hash information to produce a certain length of information summary, which can realize message authentication and integrity verification.)
