Abstract
We study Nash equilibria and the price of anarchy in the classic model of Network Creation Games introduced by Fabrikant et al. In this model every agent (node) buys links at a prefixed price a>0 in order to get connected to the network formed by all the n agents. In this setting, the reformulated tree conjecture states that for a>n, every Nash equilibrium network is a tree. Moreover, Demaine et al. conjectured that the price of anarchy for this model is constant. Since it was shown that the pri...
