“…To explain the natural incidents occurred in many scientific fields-such as the field of engineering, solid-state physics, plasma physics, applied physics, applied mathematics, plasma waves, fluid dynamics, quantum physics, electrodynamics, magneto hydrodynamics and turbulence, biology, fiber optics, chemistry, chemical physics, astrophysics, general theory of relativity, cosmology, medical science, and so on -we need to look for the exact solutions of the NLEEs. Many researchers have built up various types of methods to obtain the exact solutions for the NLEEs, including the following: the homogeneous balance method [1,2], the first integral method [3,4], the Jacobi elliptic function expansion method [5,6], the exponential function method [7,8], the tanh-function method [9,10], the auxiliary ordinary differential equation method [11], the homotopy analysis method [12], the tanh-coth method [13], the sine-Gordon expansion method [14], the (G /G 2 )-expansion method [15], the unified method [16], the variational iteration method [17], the extended direct algebraic method [18], the exp(−φ(ξ))-expansion method [19,20], Lie group method [21], the Hirota's bilinear method [22,23], the generalized Kudryshov method [24][25][26], the Backlund transform method [27], the Cole-Hopf transformation method [28], the Riccati equation method [29], the (G /G)-expansion method [30,31], the new generalized (G /G)expansion method [32], the modified (G /G)expansion method [33], and so on.…”
