20.500.12556/DKUM-66412 Spreading of cooperative behaviour across interdependent groups Recent empirical research has shown that links between groups reinforce individuals within groups to adopt cooperative behaviour. Moreover, links between networks may induce cascading failures, competitive percolation, or contribute to efficient transportation. Here we show that there in fact exists an intermediate fraction of links between groups that is optimal for the evolution of cooperation in the prisoners dilemma game. We consider individual groups with regular, random, and scale-free topology, and study their different combinations to reveal that an intermediate interdependence optimally facilitates the spreading of cooperative behaviour between groups. Excessive between-group links simply unify the two groups and make them act as one, while too rare between-group links preclude a useful information flow between the two groups. Interestingly, we find that between-group links are more likely to connect two cooperators than in-group links, thus supporting the conclusion that they are of paramount importance. social dilemma cooperation public goods biased utility interdependent networks statistical physics of social systems socialna dilema kooperacija javne dobrine pristranski donosi soodvisne mreže statistična fizika socioloških sistemov true true true Angleški jezik Slovenski jezik Članek v reviji 2017-06-23 13:02:09 2017-06-23 13:03:08 2024-05-28 10:34:53 2019-07-11 15:46:33 2013 0 0 str. 1-6 Letn. 3 2013 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2045-2322 53 18727432 20022792 10.1038/srep02483 2045-2322 URN:SI:UM:DK:KESBTHZ3 Scientific_Reports_2013_Jiang,_Perc_Spreading_of_cooperative_behaviour_across_interdependent_groups.pdf Scientific_Reports_2013_Jiang,_Perc_Spreading_of_cooperative_behaviour_across_interdependent_groups.pdf 1 7A385A1D38BF2965268CE8C766EE4FBC f148f08029cf5c514708c10402e21f1bd9dda0b81cd296692bc2bb703eee9bf6 4b4a6672-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=113047 http://www.nature.com/articles/srep02483 1 https://dk.um.si/Dokument.php?lang=slv&id=113046 Fakulteta za naravoslovje in matematiko 0 0 0
