Caldarelli, Guido and Capocci, Andrea and Garlaschelli, Diego A self-organized model for network evolution. The European Physical Journal B, 64 (3-4). pp. 585-591. ISSN 1434-6028 (2008)Full text not available from this repository.
Here we provide a detailed analysis, along with some extensions and additonal investigations, of a recently proposed  self-organized model for the evolution of complex networks. Vertices of the network are characterized by a fitness variable evolving through an extremal dynamics process, as in the Bak-Sneppen  model representing a prototype of Self-Organized Criticality. The network topology is in turn shaped by the fitness variable itself, as in the fitness network model . The system self-organizes to a nontrivial state, characterized by a power-law decay of dynamical and topological quantities above a critical threshold. The interplay between topology and dynamics in the system is the key ingredient leading to an unexpected behaviour of these quantities.
