Effects of Empathy on the Evolutionary Dynamics of Fairness in Group-Structured Systems

Figure 3

The changing trends of the mean offer p and demand q with the level of empathy α. (a) p decreases with α for all values of mutation probability u. (b, d) q increases with α for all u. (c) p increases with α for very low u but decreases with α for intermediate u. Parameters: , , , and , with in (a, b) and in (c, d).
