“…Finally, we note that our results strongly supports preceding works on how different types of heterogeneity, regardless of origin, promote cooperation [23,[57][58][59][60][61][62][63][64][65][66][93][94][95]. While game heterogeneity does offer advantages to both cooperators and defectors, only the former can reap long-term benefits.…”

Evolutionary mixed games in structured populations: Cooperation and the benefits of heterogeneity

Evolutionary games on networks traditionally involve the same game at each interaction. Here we depart from this assumption by considering mixed games, where the game played at each interaction is drawn uniformly at random from a set of two different games. While in well-mixed populations the random mixture of the two games is always equivalent to the average single game, in structured populations this is not always the case. We show that the outcome is in fact strongly dependent on the distance of separation of the two games in the parameter space. Effectively, this distance introduces payoff heterogeneity, and the average game is returned only if the heterogeneity is small. For higher levels of heterogeneity the distance to the average game grows, which often involves the promotion of cooperation. The presented results support preceding research that highlights the favorable role of heterogeneity regardless of its origin, and they also emphasize the importance of the population structure in amplifying facilitators of cooperation.

“…In the case of the PGG [16] it is assumed that each of the groups in which the game is played is automatically defined by considering each player and all of p-1 her neighbors in the network. Following this recipe, several mechanisms aimed at further enhancing cooperation on SF networks have been investigated [20][21][22][23][24][25][26][27]. However, the structure of most real networks [28] reveals that the above assumption about the structure of the interaction groups does not hold.…”

Abstract. -In this Letter we present a new perspective for the study of the Public Goods games on complex networks. The idea of our approach is to consider a realistic structure for the groups in which Public goods games are played. Instead of assuming that the social network of contacts self-defines a group structure with identical topological properties, we disentangle these two interaction patterns so to deal with systems having groups of definite sizes embedded in social networks with a tunable degree of heterogeneity. Surpisingly, this realistic framework, reveals that social heterogeneity may not foster cooperation depending on the game setting and the updating rule.

“…The mechanism of heterogeneous investment of players in the public goods game enables players to invest different amount of resources into games by considering the difference among participants [48,49]. Lei et al [48] investigate the effect of heterogeneous investment on the evolution of cooperation in PGG by proposing a model in which the player allocates different amount of resources to its direct neighbors according to the difference of their connectivity.…”

“…Lei et al [48] investigate the effect of heterogeneous investment on the evolution of cooperation in PGG by proposing a model in which the player allocates different amount of resources to its direct neighbors according to the difference of their connectivity. It is mainly found that when the number of resources allocated to diverse neighbors have larger difference, the cooperation can be promoted.…”
