“…The explicit solutions of NLEEs play a prominent role in the study of nonlinear science. Various effective procedure have been developed to solve NLEEs, like the inverse scattering transform [1], the Darboux transformation [2], Backlund transformation [3], the unified method (UM) and its generalized form (GUM) [4, 5] and Hirota bilinear form method [6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25]. The Hirota's bilinear method is one of the most direct and convenient method to obtain the exact soliton solution of NLEEs.…”
