(a) The average level of prejudice vs. in-group mixing for different in-group learning rates and (b) the average cooperation vs. in-group mixing for different in-group learning rates. Si and Pi are a-priori fixed for all agents, and results represent the average of 10 randomly seeded runs, each conducted for 50,000 generations. Initial configuration involves αi = 0, i. Mutation applied at the rate μ = 1/100 to each variable di, si, ui and αi. Five equally sized sub-populations are assumed.
