20.500.12556/DKUM-66540 Does strong heterogeneity promote cooperation by group interactions? Previous research has highlighted the importance of strong heterogeneity for the successful evolution of cooperation in games governed by pairwise interactions. Here we determine to what extent this is true for games governed by group interactions. We therefore study the evolution of cooperation in the public goods game on the square lattice, the triangular lattice, and the random regular graph, whereby the payoffs are distributed either uniformly or exponentially amongst the players by assigning to them individual scaling factors that determine the share of the public good they will receive. We find that uniformly distributed public goods are more successful in maintaining high levels of cooperation than exponentially distributed public goods. This is not in agreement with previous results on games governed by pairwise interactions, indicating that group interactions may be less susceptible to the promotion of cooperation by means of strong heterogeneity than originally assumed, and that the role of strongly heterogeneous states should be reexamined for other types of games. social dilemmas cooperation public goods inequality social diversity socialne dileme kooperacija javne dobrine neenakost socialna diverziteta true true true Angleški jezik Slovenski jezik Članek v reviji 2017-06-30 12:20:40 2017-06-30 12:22:19 2024-05-28 10:04:31 2019-07-11 15:50:52 2011 0 0 str. 1-12 Letn. 13 2011 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1367-2630 530.16 21135621 18843144 10.1088/1367-2630/13/12/123027 1367-2630 URN:SI:UM:DK:VHVHU9CK New_Journal_of_Physics_2011_Perc_Does_strong_heterogeneity_promote_cooperation_by_group_interactions.pdf New_Journal_of_Physics_2011_Perc_Does_strong_heterogeneity_promote_cooperation_by_group_interactions.pdf 1 C5ECAF6AB6B699CCD8AB74451AA2472E 0cdc6685835aa4234197a6691208808ae8089dddbb642a8bc652646d1b638630 53f87ab1-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=113395 http://stacks.iop.org/1367-2630/13/i=12/a=123027?key=crossref.557e09e1ba88d57521aa3418de59e5f5 1 https://dk.um.si/Dokument.php?lang=slv&id=113394 Fakulteta za naravoslovje in matematiko 0 0 0
