Table 2:
Default settings for the MPB, where the term “change frequency (u)” means that the environment changes every u fitness evaluations, S denotes the range of allele values, and I denotes the initial height for all peaks. The height of peaks is shifted randomly in the range and the width of peaks is shifted randomly in the range .
