Cultural diversity for different models (Axelrod's, Flache's, and ours).

X-axis displays levels of noise; Y-axis displays normalized cultural diversity. Each colored line symbol denotes one of three models, i.e. Axelrod's (continuous red), Flache's (continuous blue), ours with α = 0.9 and α' = 0.5 (dotted black) and ours with α = 0.8 and α' = 0.5 (dotted gray). 95% confidence intervals are displayed only when exceeding the size of the line symbol. Data points are averages of 50 repetitions per territory with 100,000 iterations per agent.
