Network, mathematically known as the graph, the earliest study began in 1736 Euler's Königsberg seven bridges problem, but later on the study of the graph developed slowly, until 1936, only the first book on the study of graph theory. In the 1960s, two Hungarian mathematicians, Erdos and Renyi, established the theory of random graphs, which was recognized as a systematic study of the complex network theory in mathematics. For the next 40 years, random
