“…In recent few decades, many efficient methods or techniques have been used to find the analytical solutions for nonlinear models, such as the Ricatti approach 21 , the Kudryashov method 22 , the Darboux transformation 23 , the Jacobi elliptic function approach 24 , the sine-cosine approach 25 , the direct algebraic technique 26 , the extended tanh function method 27 – 31 , sine-Gordon approach 32 , 33 , Fokas technique 34 , the Hirota bilinear transformation approach 35 , 36 , the first integral approach 37 , the trial solution technique 38 , the -expansion approach 39 , -expansion technique 40 , -expansion technique 41 – 43 , Lie Symmetry method 44 , the unified method 45 , and so on. The travelling wave solution of DSW was attained by utilizing the auxiliary equation method 46 .…”
