 The influence of age-driven investment on cooperation in spatial public goods gamesLin-Lin Tian, Ming-Chu Li, Kun Lu, Xiao-Wei Zhao and Zhen Wang Chaos, Solitons & Fractals, 2013, vol. 54, issue C, 65-70 Abstract: In social and biological systems, the individual capacity of contribution usually varies during its lifespan. In this paper, we study the effect of age-driven investment on cooperation in the public goods game under quenched age (QueA), natural aging (NatA) and strategy aging (StrA) rules. By investigating the evolutionary dynamics and the spatial distribution on a square lattice, we find that cooperator clusters become more robust under the specific age structure, in which young cooperators usually locate on the margins. The StrA rule is the most effective at enhancing cooperation because the age characteristic helps the organization of cooperators defend against the invasion of defectors. The other rules require higher synergy factors for cooperation dominance where the old and young cooperators are well-mixed. In addition, the QueA rule improves cooperation by accelerating the extinction of defectors and the NatA rule performs the worst because the aging process breaks up the cooperative clusters. Our results may provide insight into the impact of age-dependent contributions on cooperative behaviors in real world situations.
