Economic small-world behavior in weighted networks

  title={Economic small-world behavior in weighted networks},
  author={Vito Latora and Massimo Marchiori},
The small-world phenomenon has been already the subject of a huge variety of papers, showing its appeareance in a variety of systems. However, some big holes still remain to be filled, as the commonly adopted mathematical formulation is valid only for topological networks. In this paper we propose a generalization of the theory of small worlds based on two leading concepts, efficiency and cost, and valid also for weighted networks. Efficiency measures how well information propagates over the… CONTINUE READING
