چکیده
Submitted: Mar 2, 2013; Accepted: Apr 10, 2013; Published: Jun 10, 2013 Abstract: In this article, we present a variant approach of the generalized and improved (G'/G)–expansion method and construct some new exact traveling wave solutions with free parameters of the nonlinear evolution equations, via the Painleve integrable Burgers equation, the Boiti-Leon-Pempinelle equation and the Pochhammer-Chree equations. When the free parameters receive special values, solitons are originated from the travelling wave. In the new approach, G( ) satisfies the Jacobi elliptic equation in place of the second order linear equation. It is shown that the suggested algorithm is quite efficient and is practically well suited to solve these problems.
