Box-and-whisker diagram and iterative curve about the impact of different upper limit of frequency 𝑓∈[0,𝐹].

(a) Box-and-whisker after 50 independent runs with different upper limit of frequency 𝑓∈[0,𝐹], where 1–6 in abscissa axis correspond to 𝐹=0.5,1,2,…5, respectively

(b) Iterative curve after one independent run with different upper limit of frequency 𝑓∈[0,𝐹], where 1–6 in abscissa axis correspond to 𝐹=0.5,1,2,…5, respectively
