Abstract

In this paper, the variational iteration method is applied to diffusion problems. The limitations of the method with respect to the characteristics of the approximate solutions are discussed. A modification of the method is proposed to partially counteract these unwanted characteristics, aiming to make the method more useful in cases where truncation of the series solution is unavoidable.
