On new traveling wave solutions of the Hirota-Satsuma coupled KdV equation

[...]the numerical simulations add to these obtained solutions. (ProQuest: ... denotes formula omitted.) 1 Introduction The mathematical modeling of scientific systems generally is expressed by nonlinear evolution equations. [...]it is crucial to reach general solutions of these corresponding nonlinear equations. [...]the general solutions of these equations provide much information about the character and the structure of the equations for researchers. [...]the improved (G'/G) -expansion method is crucial one to construct different types of the soliton solutions of the NPDEs and systems.
