Fig. A3.

Fitness trajectories on the HoC/uncorrelated landscape with fitness effect distribution $\rho (s)$ specified by a) $\beta =0.5$, b) β  =  1, and c) β  =  2. The parameter β characterizes how fast $\rho (s)$ decays with s (Equation A20). In each sub-figure, the upper panel shows the fitness trajectories as a function of actual time with (red) and without (blue) clonal interference (CI). The solid lines are are obtained from solving Equation (A24) [with λ given by Equation (A22) in the CI regime and λ  =  0 in the SSWM regime], while the dashed lines are individual replicates from simulations. The lower panel compares trajectories (blue and red solid lines in the upper panel) after rescaling time $\tilde{t}=t·A/2$ for the case with clonal interference such that both trajectories have the same derivative at t = 0.
