Box-and-whisker diagram and iterative curve about the impact of different population size  𝑝𝑠.

(a) Box-and-whisker after 50 independent runs with different population size  𝑝𝑠, where 1–9 in abscissa axis correspond to  𝑝𝑠=10,15,…,50, respectively

(b) Iterative curve after one independent run with different population size 𝑝𝑠, where 1–9 in abscissa axis correspond to 𝑝𝑠=10,15,…,50, respectively
