We present new exact solutions for the (1+1)-dimensional Kaup-Kupershmidt (KK) equation by employing method of double (G'/G, 1/G)-expansion. We express solutions by hyperbolic, trigonometric and rational functions explicitly. Computational results indicate the efficiency and applicability potential of the method.
