Abstract(s)
We investigate the influence of the update dynamics on the evolution of cooperation. Three of the most
studied games in this area are used: Prisoner’s Dilemma, Snowdrift and the Stag Hunt. Previous studies
with the Prisoner’s Dilemma game reported that less cooperators survive with the asynchronous version
of the game than with the synchronous one. On the other side, studies with the Snowdrift game are not
conclusive about this subject. Based on simulations with these three games, played on different types of
networks and using different levels of noise in the choice of the next strategy to be adopted by the agents,
we conclude that, in general, an asynchronous dynamics favors the evolution of cooperation. Results
concerning the monotonicity of these models and their sensitivity to small changes in the synchrony rate
are also reported. This work is a contribution to a better understanding of the conditions under which
cooperation can emerge and how different parameters may influence this emergence.
