 However, when the payoff matrix has values of \(T = 1.2, R = 1.1, P = 0\).1, and \(S = 0\), the evolutionary dynamics carry the population to a stable cycle oscillating between two states. In this cycle cooperators and defectors coexist, with some regions containing “blinkers” oscillating between defectors and cooperators (as seen in generation 19 and 20).
