Abstract
We investigate the efficiency of Generalized Kudryashov and improved F-expansion methods in solving nonlinear partial differential equations. The Dodd-Bullough-Mikhailov equation is considered to implement these methods. Both methods allow us to construct a number of travelling wave solutions of the governing equation. However, the Generalized Kudryashov method is found more direct, effective and requires less tedious symbolic computations compared to the improved F-expansion method. Our analysis also reveal that the basic version of either of the methods could be effective enough to acquire the fundamental wave solutions of the governing equation.
