On the arXivotubes

Salvo Assenza, Jesus Gomez-Gardenes and Vito Latora say in their e-print, “Enhancement of cooperation in highly clustered scale-free networks” (arXiv:0801.2416),

We study the effect of clustering on the organization of cooperation, by analyzing the evolutionary dynamics of the Prisoner’s Dilemma on scale-free networks with a tunable value of clustering. We find that a high value of the clustering coefficient produces an overall enhancement of cooperation in the network, even for a very high temptation to defect. On the other hand, high clustering homogenizes the process of invasion of degree classes by defectors, decreasing the chances of survival of low densities of cooperator strategists in the network.

Suddenly, with regard to cooperation issues, I have gone from [tex]N[/tex] papers behind to [tex]N + 1[/tex] papers behind. Question: If we construct a time-dependent network model of a population, can we represent both kin recognition and the effect of spatial distribution by node clustering?
