20.500.12556/DKUM-88850 Strategically positioning cooperators can facilitate the contagion of cooperation The spreading of cooperation in structured population is a challenging problem which can be observed at diferent scales of social and biological organization. Generally, the problem is studied by evaluating the chances that few initial invading cooperators, randomly appearing in a network, can lead to the spreading of cooperation. In this paper we demonstrate that in many scenarios some cooperators are more infuential than others and their initial positions can facilitate the spreading of cooperation. We investigate six diferent ways to add initial cooperators in a network of cheaters, based on diferent network-based measurements. Our research reveals that strategically positioning the initial cooperators in a population of cheaters allows to decrease the number of initial cooperators necessary to successfully seed cooperation. The strategic positioning of initial cooperators can also help to shorten the time necessary for the restoration of cooperation. The optimal ways in which the initial cooperators should be placed is, however, non-trivial in that it depends on the degree of competition, the underlying game, and the network structure. Overall, our results show that, in structured populations, few cooperators, well positioned in strategically chosen places, can spread cooperation faster and easier than a large number of cooperators that are placed badly. cooperation evolutionary game theory social physics collective dynamics complex system sodelovanje evolucijska teorija iger fizika družbe kolektivna dinamika kompleksni sistem true false true Nature Publishing Group Angleški jezik Slovenski jezik Znanstveno delo 2024-05-30 03:29:48 2024-10-22 12:34:26 2024-10-23 03:29:47 0000-00-00 00:00:00 2021 0 0 Str. 1-12 št. članka 1127 Letn. 11 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2020-08-25 2020-12-22 2021-01-13 53 47493123 10.1038/s41598-020-80770-8 2045-2322 Yang-2021-Strategically_positioning_cooperator.pdf Yang-2021-Strategically_positioning_cooperator.pdf 1 103FD8783C19697E0671364F9F0BAAF0 bda27fa9384af4ad2178552b64cfccd090aa697ecf5bdd573ffd50b461dae747 f9f0d7fb-9060-11ef-9244-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=186743 https://doi.org/10.1038/s41598-020-80770-8 0 0647cb60-9061-11ef-9244-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=186744 Fakulteta za naravoslovje in matematiko 0 0 0
