Learning, migration and evolutionary games: a new paradigm in the study of cooperation — •Carlos P. Roca1,2 and Dirk Helbing11Chair of Sociology, in particular of Modeling and Simulation, ETH Zurich, Swizterland — 2GISC, Department of Mathematics, Universidad Carlos III de Madrid, Spain

The problem of the emergence and stability of cooperative behavior has attracted a great deal of attention during last decades, being one of the most prominent open questions in a variety of disciplines [1]. Evolutionary game theory has become one of the most fruitful frameworks to address this issue, by proposing stylized models based on social dilemmas and evolutionary dynamics [2]. Only very recently the importance of migration, understood as individuals' mobility, has started to be considered in depth [3]. On the other hand, whereas most studies introduce an evolutionary dynamics based on some sort of imitation, in this work we provide individuals with basic learning capabilities. We have found that the combined effect of learning and migration has a strong influence on cooperation, which nature stands in stark contrast to that of models based on other kind of dynamics. Our work suggests that the existence of particular cognitive abilities, as well as the possibility of mobility, may have been of crucial importance in the flourishing of cooperation.
