A comparison between two different methods for solving KdV-Burgers equation. (English) Zbl 1084.65079

Summary: This paper presents two methods for finding the soliton solutions to the nonlinear dispersive and dissipative KdV-Burgers equation. The first method is a numerical one, namely the finite differences with variable mesh. The stability of the numerical scheme is discussed. The second method is the semi-analytic Adomian decomposition method. Test example is given. A comparison between the two methods is carried out to illustrate the pertinent feature of the proposed algorithm.
