一个简单的确定性有限自动机最小化算法的C++。它使用一个类来表示的DFA从文本文件中读取。的最小化是通过一个函数对象完成的，并且最小化该处被显示在控制台。

用支持向量机(SVM)实现分类与函数回归的源代码。内有实例，依湖芦画瓢即可。-Using support vector machine (SVM) classification and function to achieve the reunification of the source code. There are examples, according to Lake Lo paintings can ladle.

c语言完成的http代理，完成功能：获取浏览器的get报文；修改报文的Encoding-type; GET报文中转到web服务器，代理接收服务器的内容，解析content-length, 或trunked的http回文，再中转给浏览器。可以在应用层实现，http报文的修改。

This a simple demo of how to evaluate mathematical expressions in text format, including provision for variables and functions. The code consists of three simple classes: 1) Calc - which does the main calculations, 2) Stack - which is used to push and pop intermediate operators and numbers and 3) Symbol Table. The symbol table is a collection of calc symbols, a type structure consisting of various elements, including the expression name, function name, and the final value of the expression The evaluation procedure is done in three steps: 1) simplify the expression by removing all the elements within () and storing them in subexpressions within the symbol table. 2) Each of these sub expressions are then converted to RPN format (Reverse polar notation) and evaluated 3) Finally, the main expression is converted to RPN and evaluated-This is a simple demo of how to evaluate mathematical expressions in text format, including provision for variables and functi

RSA算法     1978年就出现了这种算法，它是第一个既能用于数据加密也能用于数字签名的算法。它易于理解和操作，也很流行。算法的名字以发明者的名字命名：Ron Rivest, AdiShamir 和Leonard Adleman。但RSA的安全性一直未能得到理论上的证明。     RSA的安全性依赖于大数难于分解这一特点。公钥和私钥都是两个大素数（大于100个十进制位）的函数。据猜测，从一个密钥和密文推断出明文的难度等同于分解两个大素数的积。     密钥对的产生。选择两个大素数，p 和q 。计算：n
