Examples of how assortment changes with the frequency of cooperators within single simulation runs. (a) Baseline scenario without selection (s = 0). (b) Baseline scenario with selection (s = 0.5). In both cases cost-benefit ratios were set to 0.5, simulations were initialized with a population of defectors and depicted dynamics comprise 25,000 simulated time steps.
