20.500.12556/DKUM-66399 If players are sparse social dilemmas are too: importance of percolation for evolution of cooperation Spatial reciprocity is a well known tour de force of cooperation promotion. A thorough understanding of the effects of different population densities is therefore crucial. Here we study the evolution of cooperation in social dilemmas on different interaction graphs with a certain fraction of vacant nodes. We find that sparsity may favor the resolution of social dilemmas, especially if the population density is close to the percolation threshold of the underlying graph. Regardless of the type of the governing social dilemma as well as particularities of the interaction graph, we show that under pairwise imitation the percolation threshold is a universal indicator of how dense the occupancy ought to be for cooperation to be optimally promoted. We also demonstrate that myopic updating, due to the lack of efficient spread of information via imitation, renders the reported mechanism dysfunctional, which in turn further strengthens its foundations. cooperation public goods punishment phase transitions physics of social systems kooperacija javne dobrine kazen fazni prehodi fizika socialnih sistemov true true true Angleški jezik Slovenski jezik Članek v reviji 2017-06-23 11:10:54 2017-06-23 11:11:50 2024-05-28 11:00:22 2019-07-11 15:46:09 2012 0 0 str. 1-6 Letn. 2 2012 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2045-2322 530.16 18727432 19099656 10.1038/srep00369 2045-2322 URN:SI:UM:DK:8LFFRF8S Scientific_Reports_2012_Wang,_Szolnoki,_Perc_If_players_are_sparse_social_dilemmas_are_too_Importance_of_percolation_for_evolution_of_co.pdf Scientific_Reports_2012_Wang,_Szolnoki,_Perc_If_players_are_sparse_social_dilemmas_are_too_Importance_of_percolation_for_evolution_of_co.pdf 1 572CADFEDE337F49DCAD613C0BB6A19C 177e00aa8d5ecc56f545348fd99a5a5a3734a2e7f42d7f2618c143a531564bf6 4a3f5de2-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=113017 http://www.nature.com/articles/srep00369 1 https://dk.um.si/Dokument.php?lang=slv&id=113016 Fakulteta za naravoslovje in matematiko 0 0 0
