Revised Figure S3 - Optimal replacement types. Relative fitness ω of replacement type τ1 = age-dependent against τ2 = random for the three different pathogen environments (standard (blue), positively correlated (red), random (green)) given a total memory pool size of nmp = 25 A and nmp = 5 C, respectively. The solid line denotes the average value for ω over 15 simulations. The shaded area corresponds to the estimated pointwise 95%-confidence intervals. B, D. Average frequency of individuals with replacement type τ1 in the total population at t = 20000.
