Exact solutions for a generalized burgers-Fisher equation

The hyperbolic function method was used to study new exact travelling wave solutions for a class of nonlinear evolution equation. The basic idea of this method is based on the fact that solitary wave solution of the nonlinear evolution equations are essentially of a localized property. Because the travelling wave solution can be assumed as the polynomial form of the hyperbolic functions, the resultant solutions were obtained by solving a system of nonlinear algebraic equations.
