The Evolution of Cooperation is Affected by the Persistence of Fitness Effects, the Neighborhood Size and their Interaction.

摘要: Evolutionary Game Theory and the Prisoner's Dilemma (PD) in particular have been used to study evolution of cooperation. We consider a population asexually reproducing, age-structured individuals two-dimensional square lattice structure. The employ fixed cooperative or defecting strategies towards their neighbors repeating interactions accumulate reproductive fitness. focus on effects persistence past interactive neighborhood size show that larger sizes are generally detrimental cooperation fitness decreases likelihood small neighborhoods. However, for effect is reversed. Thus, our corroborates earlier studies structure increases evolutionary potential behavior PD paradigm. This finding may explain heterogeneity previous results cautions outcomes needs be considered analyses behavior. pairwise vary dramatically biological social systems could profound various contexts.
