n this article, we apply the homotopy perturbation method (HPM) to obtain approximate analytical solutions
of the generalized Burger and Burger-Fisher (B–F) equations. Several numerical examples are given
to illustrate the efficiency of the HPM. Comparison of the result obtained by the present method with exact
solution reveals that the accuracy and fast convergence of the new method. It is predicted that the HPM
can be found wide application in engineering problems.
