In this paper, approximate-exact solutions of a class of Lane-Emden type singular IVPs problems, by the variational iteration method, are presented. The variational iteration method yields solutions in the forms of convergent series with easily calculable terms. The scheme is shown to be highly accurate, and in some cases, yields exact solutions in few iterations. (C) 2008 Elsevier Ltd. All rights reserved.
