Reliable approaches of variational iteration method for nonlinear operators
In this paper, new approaches of the variational iteration method are developed to handle nonlinear problems. The proposed approaches are capable of reducing the size of calculations and easily overcome the difficulty arising in calculating complicated integrals. Numerical examples are examined to show the efficiency of the techniques. The modified approaches show improvements over the existing numerical schemes. (C) 2007 Elsevier Ltd. All rights reserved.
