Mobility, fitness collection, and the breakdown of cooperation.

摘要: The spatial arrangement of individuals is thought to overcome the dilemma cooperation: When cooperators engage in clusters, they might share benefit cooperation while being more protected against noncooperating individuals, who from but save cost cooperation. This paradigmatically shown by prisoner's model. Here, we study this model one and two dimensions, explicitly take into account that biological setups, fitness collection selection are separated processes occurring mostly on vastly different time scales. separation particularly important understand impact mobility evolution We find even small diffusive strongly restricts since it enables noncooperative invade cooperative clusters. Thus, most scenarios, where competing an irrefutable fact, alone cannot explain stable cooperation, additional mechanisms necessary for structure promote breakdown analyzed detail. confirm existence a phase transition, here controlled costs, which distinguishes between purely absorbing states. While dimension class voter model, belongs directed percolation universality dimensions.
