  • Title: Does mobility decrease cooperation?
    Author: Vainstein MH, T C Silva A, Arenzon JJ.
    Journal: J Theor Biol; 2007 Feb 21; 244(4):722-8. PubMed ID: 17055534.
    Abstract:
    We explore the minimal conditions for sustainable cooperation on a spatially distributed population of memoryless, unconditional strategies (cooperators and defectors) in presence of unbiased, non-contingent mobility in the context of the Prisoner's Dilemma game. We find that cooperative behavior is not only possible but may even be enhanced by such an "always-move" rule, when compared with the strongly viscous ("never-move") case. In addition, mobility also increases the capability of cooperation to emerge and invade a population of defectors, what may have a fundamental role in the problem of the onset of cooperation.
