Network Growth via Preferential Attachment based on Prisoner's Dilemma Game

Original · EN

In this article we discuss network growth based on Prisoner's Dilemma(PD) where palyers on nodes in a network palay with its linked players. The players estimate total profits in the PD. When a new node is attached, the node make linkes to nodes in the network with the probabilities in proportion to the profits made by the game. Iterating this process, a network grows. We investigate properties of this type of growing networks, especially the degree distribution and time-depending strategy distribution by running computer simulation. We also find a sort of phase transition in the strategy distributions. For these phenomena given by computer simulation, theoretical studies are also carried out.
