An enhanced of the (G'/G) -expansion method combined with Liu's theorem is proposed to construct new exact solutions of the nonlinear (1+1)-dimensional Drinfel'd-Sokolov-Wilson equation (DSW). As a result, more and new general exact solutions are obtained including hyperbolic function solutions, trigonometric function solutions and rational function solutions. New complex type solutions to the nonlinear (1+1) dimensional (DSW) equation are obtained with Liu's theorem.
