20.500.12556/DKUM-35943 Coherence resonance in a spatial prisoner's dilemma game We study effects of additive spatiotemporal random variations, introduced to the payoffs of a spatial prisoner's dilemma game, on the evolution of cooperation. In the absence of explicit payoff variations the system exhibits a phase transition from a mixed state of cooperators and defectors to a homogenous state of defectors belonging to the directed percolation universality class. By introducing nonzero random variations to the payoffs, this phase transition can be reverted in a resonance-like manner depending on the variance of noise, thus marking coherence resonance in the system. We argue that explicit random payoff variations present a viable mechanism that promotes cooperation for defection temptation values substantially exceeding the one marking the transition point to homogeneity by deterministic payoffs. dynamic systems noise spatiotemporal noise intensity spatial resonance inherent spatial resonance spatial decoherence excitable media dinamični sistemi ekscitabilni sistemi resonanca intenziteta hrupa prostorska resonanca inherentna prostorska resonanca prostorska dekoherenca true true true Angleški jezik Slovenski jezik Članek v reviji 2012-06-07 12:38:09 2012-06-07 12:38:09 2024-02-16 09:01:53 2021-04-15 03:36:57 2006 0 0 str. 1-9 Letn. 8 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1367-2630 534.83:531.3 21135621 14504456 10.1088/1367-2630/8/2/022 1367-2630 URN:SI:UM:DK:NIQJWOVM New_Journal_of_Physics_2006_Perc_Coherence_resonance_in_a_spatial_prisoner_s_dilemma_game.pdf New_Journal_of_Physics_2006_Perc_Coherence_resonance_in_a_spatial_prisoner_s_dilemma_game.pdf 1 B93B5DAED0DB434AE8A979569F9BC8C1 fc67602dedb1e0c24c6db69fc2851ec775e52b2e057bfc342c7d01f1f6b232ff 53bd1020-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/186436d6-287a-40fb-b87e-bef4a3302a52 https://dk.um.si/Dokument.php?lang=slv&id=113385 http://stacks.iop.org/1367-2630/8/i=2/a=022?key=crossref.93a1ff2b420d3eec97d130607992cc8d 1 https://dk.um.si/Dokument.php?lang=slv&id=46979 Fakulteta za naravoslovje in matematiko 0 0 0
