Interaction between games give rise to the evolution of moral norms of cooperation
Fig 12
The density of different strategies in the reputation-based model with three archetypal games in a structured population.
The time average density of different strategies, as a function of the probability of error in inferring the PD strategy of the opponent, η, are plotted. The payoff values used for the games are presented in Table 1. Simulations are performed in a population of size 40000 individuals residing on a 200 × 200 square lattice with first nearest neighbor von Neumann connectivity and periodic boundaries. The simulations are performed for 6000 time steps, and averages and standard deviations are calculated based on the last 4000 time steps. The simulations start from random initial conditions. Here, ν = 0.005.
