应用背景 Fifty Years of Shannon Theory： A brief chronicle is given of the historical development of the central problems in the theory of fundamental limits of data compression and reliable communication. 关键技术Shannon’s A mathematical theory of communication”published in July and October of 1948 is the Magna Carta of the information age. Shannon’s discoveryof the fundamental laws of data compression and transmission marks the birth of Information Theory. A unifying theory with profound intersections with Probability, Statistics, Computer Science, and other fields, Information Theory continues to set the stage for the development of communications, data storage and processing, and other information technologies.

这是一个支持多位数运算（可以达到几百位的长整数）的数类，名字叫Long，它是从long类发展过来的，但比原来的long类功能多。Long类可以和原有的double，long等等数据类型混合运算-This is a multi-digit support operations (which may reach hundreds of long integers) to a number of named Long, it is long from over the type of development, but more than the original multi-functional long. Long classes can be double the original, long data types, etc. Operational mixed

用C++实现求解图的边介数，文件中包含.h和.cpp文件，输入文件是txt文件：点的个数以及具体的边，例子请见压缩文件中node.txt。该程序是能够运行成功的，对学习复杂网络的初学者有一定的帮助。
