-expansion method and the exp
-expansion method with the aid of a suitable transformation. We employ these two methods to derive families of exact solutions for a higher order dispersive nonlinear Schrödinger equation describing the propagation of the optical pulse in a medium. Comparison between these two methods is presented. We show that the two methods as well as their results are equivalent.Copyright © 2026 Author(s) retain the copyright of this article.
