We consider the generalized Benjamin-Bona-Mahony-Burgers equation to construct exact solutions by employing the improved system technique. We believe that the improved system technique is effective and stable to find exact solutions of nonlinear partial differential equations as well as the considered equation. Moreover, we perform meaningfully the behaviors of the obtained solutions under suitable physical variable coefficients. (C) 2017 The Authors. Published by Elsevier B.V.
