“…However, there have been few numerical techniques which treats this types of problems. These methods include collocation methods [5], finite difference method [12,14], sinc Galerkin [20], non-polynomial spline functions [46], octic spline functions [47], quintic spline [33], Adomian decomposition method [55,56], reproducing kernel space method [4], differential quadrature method [35], variational iteration method [1,45], differential transformation method [22], Homotopy perturbation method [25,40,43], and the Galerkin residual technique with Bernstein and Legendre polynomials [30]. Recently, El-Gamel and Abdrabou [16] proposed a new approach for solving eight-order boundary value problems via sinc-Galerkin.…”
