Numerical comparisons for the fractional order $\mathit{\alpha }\mathbf{=}\mathbf{0.5}\mathbf{,}\mathbf{0.6}\mathbf{,}\mathbf{0.7}$ and 0.8: FABM ( $\mathit{h}\mathbf{=}\mathbf{0.001}$ ), MsGDTM ( $\mathit{h}\mathbf{=}\mathbf{0.001}$ ) and P-MsGDTM ( $\mathit{h}\mathbf{=}\mathbf{0.01}$ ) in Example 1.
