Effect of Homophily on Network Evolution

Kim, Kibae; Altmann, Jörn - Technology Management, Economics and Policy Program … - 2015

As empirical studies have found that large complex networks (e.g., WWW) are scale-free, the preferential attachment model is commonly applied to generate this network topology. This model assumes a node with higher degree is more likely to gain a new link, and ignore node attributes except the...

Growing network: Models following nonlinear preferential attachment rule

Zadorozhnyi, V.N.; Yudin, E.B. - In: Physica A: Statistical Mechanics and its Applications 428 (2015) C, pp. 111-132

We investigate the preferential attachment graphs proceeding from the following two assumptions. The first one: the probability that a new vertex connects to a vertex i is proportional to an arbitrary nonnegative function f of a vertex degree k. The second assumption: a new vertex can have a...
