“…Therefore, numerical and approximation techniques have been used for solving these equations. Some of the most common methods are homotopy perturbation method [39], Haar wavelet method [40], Spline collocation method [41], fractional difference method (FDM) [42], power series method [43], Adomian decomposition method (ADM) [44], Kronecker convolution product [45], spectral methods [46], He's variational iteration method [47], and homotopy analysis method [48].…”
