摘要：
We analyze the discrete nonlinear Schrodinger equation with a saturable nonlinearity through the (G'/G)-expansion method to present some improved results. Three types of analytic solutions with arbitrary parameters are constructed; hyperbolic, trigonometric, and rational which have not been explicitly computed before. (C) 2011 Elsevier B.V.
