Abstract	Višeagentne simulacije na polju evolucijske teorije igara pokazuju da mehanizam direktnog reciprociteta dobro funkcionira u malim grupama gdje se agenti susreću često i gdje prevaranti ne mogu proći nekažnjeno. Ipak, nigdje do sad nije kvantitativno objašnjeno pod kojim uvjetima direktni reciprocitet ustupa mjesto indirektnom reciprocitetu. Za razliku od ranijih modela, simulacijski model predložen u ovom radu uzima u obzir memorijske sposobnosti agenata, kao i energetsku cijenu takvih sposobnosti. Pokazalo se da veličina grupe raste s memorijskim kapacitetom agenata upravo kao što ukazuju Dunbarovi empirijski podaci. Štoviše, utvrđeno je da vrijeme dostizanja izrabljivača raste asimptotski s veličinom grupe što upućuje na zaključak da postoji granična veličina grupe iznad koje direktni reciprocitet nije dostatan za održanje suradnje i iznad koje je agentima potrebno omogućiti horizontalni prijenos informacija o izrabljivačima koji su prisutni u populaciji.
Abstract (english)	Multi-agent simulations applied to the evolutionary game theory show that the mechanism of direct reciprocity operates well within small groups of agents where it would be hard to get away with cheating one another. However no research has been done yet to explain quantitatively under which conditions direct reciprocity gives place to indirect reciprocity. Unlike previous models, our model takes into account the memory of the agents as well as the cost of having such memory. It was shown that the group size grows with the memory capacity of agents exactly as Dunbar's empirical data points to. Moreover, it was shown that time required for the cooperators to reach the defectors increases asymptotically with the group size which points to the conclusion that there is a group size limit over which the direct reciprocity is insufficient to maintain the cooperation and above which it is necessary to allow the horizontal transmission of the information about the defectors present in the population.
