This thesis investigates the emergence of collective behavior in a simu- lated predator-prey ecosystem using neuroevolution, specifically the NEAT algorithm. The study employs a multi-stage evolutionary process, including independent evolution and coevolution of predator and prey agents. Re- sults demonstrate the effectiveness of neuroevolution in evolving adaptive behaviors, with predators improving hunting strategies and prey develop- ing typical patterns of collective behavior, such as swarming. The research contributes to understanding the adaptive significance of collective behavior in predator-prey systems and highlights the potential of neuroevolution in studying emergence of complex behavior in real world.

• Title: Raziskovanje nastanka skupinskega vedenja skozi nevroevolucijo

Abstract

Ta disertacija preučuje pojav skupinskega vedenja v simuliranem ekosistemu, v katerem sobivajo plenilci in plen, z uporabo nevroevolucije, natančneje algoritma NEAT. Študija uporablja večstopenjski evolucijski proces, vključno z neodvisno evolucijo in koevolucijo agentov plenilcev in plena. Rezultati kažejo učinkovitost nevroevolucije pri razvoju prilagodljivih vedenj, pri čemer plenilci izboljšujejo lovske strategije, razvije tipične vzorce skupinskega vedenja, kot je na primer rojenje. Raziskava prispeva k razumevanju evolucije skupinskega vedenja v sistemih plenilec-plen in pokaže potencial nevroevolucije pri preučevanju nastanka pojavov skupinskega vedenja v naravi.
