Abstract

Extend the condition to constructing the three-solitary wave solution of the regularized long-wave (RLW) equation which applies the Hirota direct method to obtain analytic solutions of the RLW equation. Considering a transformation of the RLW equation to the Hirota bilinear form and applying the Hirota perturbation to this equation. The exact three-solitary wave solutions of the RLW obtained results.
