Application of variational iteration method to the generalized Burgers–Huxley equation

In this paper, He’s variational iteration method (VIM) is applied to the generalized Burgers–Huxley equation. The VIM produces an approximate solution of the equation without any discretization. The VIM is based on the incorporation of a general Lagrange multiplier in the construction of correction functional for the equation. Comparisons with the Adomian decomposition method (ADM) reveal that the VIM is very effective and convenient.
