Multiple-soliton solutions of the nonlinear partial differential equation

In this paper we improve some key steps in the homogeneous balance method, then by using this method we are able to obtain multiple soliton solutions of some nonlinear partial differential equations. This makes methods of solving nonlinear partial differential equations become more direct; furthermore, many steps of this method can be performed by computer.
