为VB中使用SINE 256加密算法的可视化操作示例源程序，貌似很强大的加密功能，当然也可以解密了。可以对文本、字符进行加密，也可以对指定文件加、解密，显示处理时间和曲线图-SINE 256 for the VB encryption algorithm used in the visual operation of the sample source code, seemingly a very strong encryption, of course, can be declassified

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 ti

PEG算法是在编码构造方面的一种有效的方法，它基于Tanner图，能有效的增大围长，使得构造出来的码的性能更好-PEG algorithm is constructed in terms of an effective coding method, based on Tanner graph, which can effectively increase the girth, making the code constructed with better performance
