Abstract
The Ritz variational method has been applied to the nonlinear partial differential equation to construct a model for travelling wave solution. The spatially periodic trial function was chosen in the form of combination of Jacobian Elliptic functions, with the dependence of its parameters

It is clear that different methods usually give different types of exact solutions
The multi-linear variable separation approach has been proved very powerful in finding variable separation solutions for a large number of PDEs
Summary
To find exact solutions of Nonlinear Partial Differential Equations (PDEs) is an important but difficult task. Many methods have been established to find exact solutions of PDEs especially for integrable systems. It is clear that different methods usually give different types of exact solutions. Similar classes of solutions can be obtained by several approaches.
