20.500.12556/DKUM-35956 Evolutionary and dynamical coherence resonances in the pair approximated prisoner's dilemma game Stochasticity has recently emerged as being a potent promoter of cooperative behaviour in systems developed under the framework of evolutionary game theory. In the spatial prisoner's dilemma game, the fitness of players adopting the cooperative strategy was found to be resonantly dependent on the intensity of payoff fluctuations. Evidently, the phenomenon resembles classical coherence resonance, whereby the noise-induced order, or coherence, of the dynamics is substituted with the noise-induced prevalence of the 'good' strategy, thus marking a constructive effect of noise on the system. The connection between the former 'dynamical' coherence resonance and the latter so-called 'evolutionary' coherence resonance, however, has not yet been established. The two different definitions of coherence resonance appear to provoke some discomfort. The goal of the present paper is therefore, on one hand, to draw a clear line between the two different perceptions of coherence resonance, and on the other, to show that the two apparently disjoint phenomena, that are currently related only by name, can in fact be observed simultaneously, sharing an identical mechanism of emergence. 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 12:39:39 2012-06-07 12:39:39 2024-02-16 09:03:59 2021-04-15 03:36:56 2006 0 0 str. 1-13 Letn. 8 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1367-2630 534.83:531.3 21135621 14822920 10.1088/1367-2630/8/8/142 1367-2630 URN:SI:UM:DK:BPGVYCI3 RAZ_Perc_Matjaz_i2006.pdf RAZ_Perc_Matjaz_i2006.pdf 1 AD169C89E0D71977896ED83A8CB4EFB7 b305e7f24c1a25e43ad0969578b70816a74b5b5fb582187bb49e677f6f41e4ca 55149cd3-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/654bf372-e272-4594-a34f-9806d601157c https://dk.um.si/Dokument.php?lang=slv&id=113440 http://stacks.iop.org/1367-2630/8/i=8/a=142?key=crossref.f8327708ee344ae54ea873cb2ba42eb6 1 https://dk.um.si/Dokument.php?lang=slv&id=46993 Fakulteta za naravoslovje in matematiko 0 0 0
