20.500.12556/DKUM-66560 Punish, but not too hard: how costly punishment spreads in the spatial public goods game We study the evolution of cooperation in spatial public goods games where, besides the classical strategies of cooperation (C) and defection (D), we consider punishing cooperators (PC) or punishing defectors (PD) as an additional strategy. Using a minimalist modeling approach, our goal is to separately clarify and identify the consequences of the two punishing strategies. Since punishment is costly, punishing strategies lose the evolutionary competition in case of well-mixed interactions. When spatial interactions are taken into account, however, the outcome can be strikingly different, and cooperation may spread. The underlying mechanism depends on the character of the punishment strategy. In the case of cooperating punishers,increasing the fine results in a rising cooperation level. In contrast, in the presence of the PD strategy, the phase diagram exhibits a reentrant transition as the fine is increased. Accordingly, the level of cooperation shows a non-monotonous dependence on the fine. Remarkably, punishing strategies can spread in both cases, but based on largely different mechanisms, which depend on the cooperativeness (or not) of punishers. evolutionary game theory public goods spatial games punishment social systems moral evolucijska teorija iger družbena lastnina prostorske igre kazen sociološki sistemi morala true true true Angleški jezik Slovenski jezik Članek v reviji 2017-07-03 10:07:18 2017-07-03 10:08:28 2024-05-27 14:38:27 2019-07-11 15:51:30 2010 0 0 str. 1-15 Letn. 12 2010 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1367-2630 53:33 21135621 14377750 10.1088/1367-2630/12/8/083005 1367-2630 URN:SI:UM:DK:IRCRYSA7 New_Journal_of_Physics_2010_Helbing_et_al._Punish,_but_not_too_hard_how_costly_punishment_spreads_in_the_spatial_public_goods_game.pdf New_Journal_of_Physics_2010_Helbing_et_al._Punish,_but_not_too_hard_how_costly_punishment_spreads_in_the_spatial_public_goods_game.pdf 1 533591778CE44C835C937DCAC25C3C5A ff7bf99e212ebf959731db01549c6bfd68fa58bff9bcbb38ef4ead0d991118e8 559c8d06-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=113457 http://stacks.iop.org/1367-2630/12/i=8/a=083005?key=crossref.77dc5c47ba40519fa052a6b641ce4661 1 https://dk.um.si/Dokument.php?lang=slv&id=113456 Fakulteta za naravoslovje in matematiko 0 0 0
