From: When agreement-accepting free-riders are a necessary evil for the evolution of cooperation
Acceptors reduce cooperation when an apology-forgiveness mechanism is introduced; defective acceptors take over the population when the apology cost is too low in RC games. Composition of the recurrent sets for RC repeated games with forgiveness. Same as Fig. 1 but for RC repeated games as a function of α and γ. Dotted (plain) sectors represent strategies that (do not) include apology. We assumed \(\epsilon \) = 0.25 and δ = 4.
