20.500.12556/DKUM-35871 Noise-guided evolution within cyclical interactions We study a stochastic predator-prey model on a square lattice, where each of the six species has two superior and two inferior partners. The invasion probabilities between species depend on the predator-prey pair and are supplemented by Gaussian noise. Conditions are identified that warrant the largest impact of noise on the evolutionary process, and the results of Monte Carlo simulations are qualitatively reproduced by a four-point cluster dynamical mean-field approximation. The observed noise-guided evolution is deeply routed in short-range spatial correlations, which is supported by simulations on other host lattice topologies. Our findings are conceptually related to the coherence resonance phenomenon in dynamical systems via the mechanism of threshold duality. We also show that the introduced concept of noise-guided evolution via the exploitation of threshold duality is not limited to predator-prey cyclical interactions, but may apply to models of evolutionary game theory as well, thus indicating its applicability in several different fields of research. dynamic systems stochastic processes cyclical interactions evolutionary rules flow simulations Monte Carlo simulations dinamični sistemi stohastični procesi metode Monte Carlo ciklični procesi ciklične interakcije prehranjevalna veriga simulacije pretoka evolucijski pojavi true true true Angleški jezik Slovenski jezik Članek v reviji 2012-06-07 12:31:08 2012-06-07 12:31:08 2024-05-28 13:39:16 2022-03-30 03:06:18 2007 0 0 str. 1-14 Letn. 9 2007 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1367-2630 519.83 21135621 15669000 10.1088/1367-2630/9/8/267 1367-2630 URN:SI:UM:DK:4ACNVQ4U New_Journal_of_Physics_2007_Perc,_Szolnoki_Noise-guided_evolution_within_cyclical_interactions.pdf New_Journal_of_Physics_2007_Perc,_Szolnoki_Noise-guided_evolution_within_cyclical_interactions.pdf 1 8BFF523AABA0AA547A6A36FBD43E424A f1d9d2b88d0a72a070f3afc2c319d6dfbd6f4051fec627c10d08ec78d79886a8 55511998-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/6d13da75-4b1e-4ca7-9d99-08a138cc9c11 https://dk.um.si/Dokument.php?lang=slv&id=113447 http://stacks.iop.org/1367-2630/9/i=8/a=267?key=crossref.f1d4f6fb159603c632781188f963b507 1 https://dk.um.si/Dokument.php?lang=slv&id=46898 Fakulteta za naravoslovje in matematiko 0 0 0
