Figure 2From: Cooperators Unite! Assortative linking promotes cooperation particularly for medium sized associationsFixation probability of cooperators as a function of the assortativeness of partner choice. In each case cooperation is promoted for some proportion of the ω 2 parameter range compared to random. Squares ⟨k⟩ = 4; circles ⟨k⟩ = 8. Filled symbols b = ⟨k⟩, open symbols b = 2 ⟨k⟩ . c = 1, ω 1 = 0.05 and w = 0.01 in all cases. The stand alone points represent the case when there is no network dynamics, i.e. ω 1 = ω 2 = 0.0. Dotted horizontal line represents the line above which cooperators fixate with higher than random probability.Back to article page
