“…Various methods have been proposed to explore nonlinear phenomena. For example, three-wave method [6,7], tanh method [8], Bäcklund transformation [9], Darboux transformation [10], Exp-function method [11], Hirota bilinear method [12], homogeneous balance method [13], the generally projective F-expansions [14], (G'/G)-expansion method [15], auxiliary equation method [16], Riccati equation method [17], simplest equation method [18,19], etc.…”
