Numerical comparison of methods for solving a special fourth-order boundary value problem

In this paper, we implement relatively new analytical techniques, the differential transform method, Adomian decomposition, and homotopy perturbation method, for solving a fourth-order boundary value problem. In these schemes, the solution takes the form of a convergent series with easily computable components. This paper will present a numerical comparison between the three methods for solving a fourth- order boundary value problem. The numerical results demonstrates that the new methods are quite accurate and efficient for this kind of problems. (c) 2007 Elsevier Inc. All rights reserved.
