Simulation results for symmetric recognition: (a) exclusive and (b) context inclusive. All populations converge to a monomorphic equilibrium of one of the behavioral types C, E, or S in the exclusive case (A never evolves), and C or E in the context inclusive case (A or S never evolve). Simulation results show proportion of descendant population states from random initial conditions for equal values for help conferred or harm inflicted (b = h = 1), equal costs to confer help or inflict harm (c_h = c_b = 0.2), 10000 runs with mutation (μ = 0.0001).
