“…Besides the exact solutions, different base functions are applied for many methods. Among others, collocation method [15][16][17][18][19][20], iterative splitting method [21], Galerkin method [22][23][24], heat balance integral method [25], analytical-numerical method [26], spline approximation [27], the method of lines [28], exponential finite difference method [29], Haar wavelet method [30], differential quadrature method [31,32], Taylor-Galerkin method [33] and modified Petrov-Galerkin method [34].…”
