“…Most researchers have used the semi-analytical and numerical methods such as the Runge-Kutta methods [1], finite difference methods [2], finite element methods [3] and spectral methods [4] to solve this type of equations. In recent years, for solving nonlinear differential equations, several analytical and semi-analytical methods have been established such as the variational iteration method [5,6], Adomian decomposition method [7], differential transform method [8], homotopy analysis method (HAM) [9][10][11][12][13], and the spectral-homotopy analysis (SHAM) [14,15] and more recently, the successive linearization method [16,17].…”
