The Silent Cooperator: An Epigenetic Model for Emergence of Altruistic Traits in Biological Systems

Figure 5

An illustration of a focal cell interacting with neighbors in its extended Moore neighborhood with range = 3, under 4 extreme scenarios (with ).

(a) Cooperator among cooperators, focal cell payoffs = 24

(b) Cooperator among defectors, focal cell payoffs = 0

(c) Defector among cooperators, focal cell payoffs = 24(1 + u)

(d) Defector among defectors, focal cell payoffs = 24u
