Box-and-whisker diagram and iterative curve about the impact of different parameter 𝑛𝑡.

(a) Box-and-whisker after 50 independent runs with different parameter 𝑛𝑡, where 1–8 in abscissa axis correspond to 𝑛𝑡=1000,2000,…,8000, respectively

(b) Iterative curve after one independent run with different parameter 𝑛𝑡, where 1–8 in abscissa axis correspond to 𝑛𝑡=1000,2000,…,8000, respectively
