“…Therefore, it is necessary to solve them analytically or numerically. Some of the methods to solve them analytically are the Hirota method [1], the projective Riccati equation method [2], the homogeneous balance method [3]- [5], the tanh-function method [6]- [10], the exp-function method [11], the improved F-expansion method [12], the ( ) ( ) exp ξ −Φ -expansion method [13]- [19], sine-cosine method [20], the modified simple equation method [21], the ( ) G G ′ -expansion method [22] [23], the modified extended tanh-function method with Riccati equation [24] and others. In the references [13]- …”
