“…In recent years, various direct methods were proposed to find exact solutions of nonlinear partial differential equations (NLPDEs) in general. These methods include, Bäcklund transformation (BT) [5], (G /G)-expansion method [6,7], auxiliary equation method [8][9][10][11][12], exponential function method [13,14], homogeneous balance (HB) method [15][16][17], variational iteration method [18][19][20], factorization method [21], algebraic method [22] and Weiss approach [23]. Whereas some of these methods are of general nature in the sense that they can be employed to any NLPDE, others are equation-specific.…”
