“…Thus, the methods for deriving exact solutions for the governing equations have to be developed. As a result, numerous techniques of obtaining traveling wave solutions have been developed over last three decades, such as, the tanh-coth function method, [2,3] the Kudryashov method, [4] the Exp-function method, [5][6][7][8] the modified simple equation method, [9][10][11][12] the (G′/G)-expansion method, [13][14][15][16][17][18][19][20][21][22] the exp(−Φ(ξ))-expansion method, [23,24] the Darboux transformation method, [25] the Hirota method, and [26] the differential transform method. [27][28][29][30] From our point of view, all these methods have some merits and demerits with respect to the problem considered and there is no unified method that can be used to deal with all types of NLEEs.…”
