Construction of a solitary wave solution for the generalized Zakharov equation by a variational iteration method

In this paper, the well-known He's variational iteration method (VIM) is used to construct solitary wave solutions for the generalized Zakharov equation (GZE). The chosen initial solution (trial function) can be in soliton form with some unknown parameters, which can be determined in the solution procedure. (c) 2007 Elsevier Ltd. All rights reserved.
