Figure 2From: The role of competitiveness in the Prisoner’s DilemmaContinuous space: uniform distribution. Cooperation frequencies in the TS-plane. On the left, results achieved using agents provided with \(\bar{k(0)} = 4.\) On the right, results achieved using agents provided with \(\bar{k(0)} = 8.\) Parameter S indicates the payoff obtained by cooperators that face defectors, that in turn gain a payoff equal to T (when facing cooperators)—see matrix 1. Colors indicate the averaged degree of cooperation achieved by the population. We recall that red indicates strong cooperation, while blue defection (i.e., no cooperation).Back to article page
