“…The study of the soliton solutions explores a theoretical reference for the research of nonlinear physical models, soliton control, optical switching equipment and so on. Up to now, many effective and powerful methods have been obtained for constructing the soliton solutions of the NLPDEs, such as the soliton ansatz method [5,6], the Kudryashov method [7], the Hirota's bilinear transform method [8,9], the Darboux transformation method [10,11], the extended trial equation method [12], the Lie symmetry method [13,14], the improved F-expansion approach [15], the invariant subspace method [16,17], the extended sinh-Gordon equation expansion method [18] and the new extended auxiliary equation method [19,20], the G G ¢ ( )-expansion method [21][22][23], the Expfunction method [24,25], the modified simplest equation method [26,27], the decomposition method [28,29], and so on.…”
