摘要

This letter comments on “A memristive chaotic map with only one bifurcation parameter," Nonlinear Dyn. (2024) 112:3869-3886, to point out certain incorrect or questionable statements and show that the qualitative findings about the symmetries of characteristics, represented by multiple figures in that paper, are of a trivial nature and can be easily and directly figured out from the simple equations of the 2D maps under considerations. Moreover, because of the fact that many details (e.g. the parameters used in computing of sample entropy) in the commented paper are missing, the Lyapunov exponents and sample entropy graphs contradict each other and the sample entropy diagrams can not be accepted as provided in that paper. Thus, it is obvious that the scientific value and novelty of that paper are rather low (not significant).
