Dynamics of the model in a simple set up. (A) Density of cooperator and cheat through time (i.e., population dynamics; $N_{co}$ and $N_{ch}$). (B) Proportion of cheats through time (i.e., cooperation dynamics; $N_{ch}/(N_{co}+N_{ch})$). (C) Vector field plot showing the model would have static dynamics once population densities reach carrying capacity (shown in thick black line) (a = 1, b = 0; other parameter values are listed in Supplementary Table S1).
