Query: 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.
