See more A scale-free network is a network whose degree distribution follows a power law, at least asymptotically. That is, the fraction P(k) of nodes in the network having k connections to other nodes goes for large values of k as See more There are two major components that explain the emergence of the scale-free property in complex networks: the growth and the preferential attachment. By "growth" is meant a growth process where, over an extended period of time, new nodes join an … See more Although many real-world networks are thought to be scale-free, the evidence often remains inconclusive, primarily due to the developing … See more There has been a burst of activity in the modeling of scale-free complex networks. The recipe of Barabási and Albert has been followed by several variations and generalizations and the revamping of previous mathematical works. As long as there is a See more In studies of the networks of citations between scientific papers, Derek de Solla Price showed in 1965 that the number of links to papers—i.e., the number of citations they receive—had a heavy-tailed distribution following a Pareto distribution or See more The most notable characteristic in a scale-free network is the relative commonness of vertices with a degree that greatly exceeds the average. The highest-degree nodes are often … See more Scale-free networks do not arise by chance alone. Erdős and Rényi (1960) studied a model of growth for graphs in which, at each step, two nodes are chosen uniformly at random and a link is inserted between them. The properties of these random graphs are … See more http://www.scholarpedia.org/article/Scale-free_networks
