20.500.12556/DKUM-66396 Evolution of conditional cooperation under multilevel selection We study the emergence of conditional cooperation in the presence of both intra-group and inter-group selection. Individuals play public goods games within their groups using conditional strategies, which are represented as piecewise linear response functions. Accordingly, groups engage in conflicts with a certain probability. In contrast to previous studies, we consider continuous contribution levels and a rich set of conditional strategies, allowing for a wide range of possible interactions between strategies. We find that the existence of conditional strategies enables the stabilization of cooperation even under strong intra-group selection. The strategy that eventually dominates in the population has two key properties: (i) It is unexploitable with strong intra-group selection; (ii) It can achieve full contribution to outperform other strategies in the inter-group selection. The success of this strategy is robust to initial conditions as well as changes to important parameters. We also investigate the influence of different factors on cooperation levels, including group conflicts, group size, and migration rate. Their effect on cooperation can be attributed to and explained by their influence on the relative strength of intra-group and inter-group selection. conditional cooperation public goods multilevel selection physics of social systems pogojno sodelovanje javne dobrine večplastna selekcija fizika socioloških sistemov true true true Angleški jezik Slovenski jezik Članek v reviji 2017-06-23 10:53:35 2017-06-23 10:54:40 2024-05-28 11:09:53 2019-07-11 15:46:04 2016 0 0 str. 1-13 Letn. 6 2016 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2045-2322 53 18727432 22018056 10.1038/srep23006 2045-2322 URN:SI:UM:DK:ZNOBNWAS Scientific_Reports_2016_Zhang,_Perc_Evolution_of_conditional_cooperation_under_multilevel_selection.pdf Scientific_Reports_2016_Zhang,_Perc_Evolution_of_conditional_cooperation_under_multilevel_selection.pdf 1 8713D56DA5EAA3980F2F9DDA7759AA63 c77b82fe15b0956e2ed1b82bfe071921171e777559b7b6cf710ce8006b2e52c0 49f9f52a-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=113010 http://www.nature.com/articles/srep23006 1 https://dk.um.si/Dokument.php?lang=slv&id=113009 Fakulteta za naravoslovje in matematiko 0 0 0
