From: Interdependent network reciprocity in evolutionary games
Cooperators and defectors on the two interdependent networks share exactly the same fate during the course of evolution, i.e., as soon as the density of cooperator (defector) pairs starts decreasing (increasing) on one network, the same happens on the other network.
In the legend Pi and Pe mark the corresponding pair configuration probabilities within (internal) and between (external) networks, respectively. The evolution is completely synchronous, with quantitative differences emerging only due to the applied relatively small value of β. Notably, for β → 0.5 the difference would be virtually none. Parameter values used were: r/G = 0.7, α = 0.15 and β = 0.5, at L = 300.
