The implementation of Variational Homotopy Perturbation Method for Fisher's equation

In this paper, we consider the variational homotopy perturbation method (VHPM) to obtain the exact and numerical solutions of Fisher's partial differential equation. Comparisons are made among the variational iteration method (VIM), the exact solutions and the proposed method. The results reveal that the proposed method is very effective and simple and can be applied for other nonlinear problems in mathemati- cal.
