Figure 2. Time-dependent AGoS.

(a) We plot G^A(j,t) for three different instants of evolutionary time. Each line provides a snapshot for a given moment, portraying the emergence of a population-wide (time-dependent) co-existence-like dilemma stemming from an individual (time-independent) defection dominant dilemma (PD). (b) The circles show the position of the different interior roots of G^A(j,t), whereas the solid (dark blue) line and (light blue) crosses show two independent evolutionary runs starting from 50% of Cs and Ds randomly placed in the networked population. Open (full) circles stand for unstable, x_L (stable, x_R) roots of G^A(j,t) (B  = 1.01, N  = 10³, <k> = 4 and β = 10.0).
