摘要：
In this paper, by means of variational iteration method numerical and explicit Solutions are computed for sonic fifth-order Korteweg-de Vries equations, without any linearization or weak nonlinearity assumptions. These equations are the Kawahara equation, Lax's fifth-order KdV equation and Sawada-Kotera equation. Comparison with Adomian decomposition method reveals that the variational iteration method is easier to be implemented. We conclude that the method is a promising method to various kinds of fifth-order Korteweg-de Vries equations. (C) 2007 Elsevier Ltd. All rights reserved.
