In this article, the modified simple equation method has been implemented to construct the new exact travelling wave solutions to nonlinear evolution equations. This method is very easy, direct, concise and simple to implement as compared with other existing methods. As an application, this method has been successfully implemented to construct the new exact travelling wave solutions to nonlinear Phi-four evolution equation. Since, the homogeneous balancing principle has been used, so we can claim that this method can be applied to other nonlinear partial differential equations or nonlinear evolution equations where the homogeneous balancing principle is satisfied.
