Comparison of the search ranges of the two methods. The blue line indicates the distribution of the dependent variable corresponding to the water-wave dynamics factor when the number of iterations is from 1 to 10; the orange line indicates the distribution of the dependent variable corresponding to the cosine dynamics factor when the number of iterations is from 1 to 10; the distribution of the cosine dynamics factor is much more uniform in comparison.
