      Entropy maximization as a holistic design principle for complex optimal networks 

      Venkatasubramanian, V.; Politis, Dimitris Nicolas; Patkar, P. R. (2006)
      A general holistic theory is presented for the organization of complex networks. The theory proposes that complex networks, both human-engineered and naturally evolved, are organized to meet certain design or survival ...
