“…The study of exact solutions of such mathematical models is the most exciting area of research investigation. To obtain the exact solutions of such mathematical models, recently, researchers follow different analytical methods, such as tangent hyperbolic method [2], modified extended direct algebraic method [3,4], ðG′/G 2 Þ -expansion method [5], Kudryashov method [6], Lie symmetry method [7], extended trial equation method [8], singular manifold method [9], sinh-Gordon expansion method [10], ðG′/GÞ-expansion method [11], generalized ð G′/GÞ-expansion method [12], generalized-improved ðG′/ GÞ-expansion method [13], extended generalized ðG ′ /GÞ -expansion method [14,15], and ðG′/G, 1/GÞ expansion method [16].…”
