| Abstract: | A simple
numerical example is proposed in this paperto show that the application of the smoothing
technique can posssibly resultin a substantial discrepancy markedly different from optimal
mesh in aconvex region. This demonstrates the necessity of applying
mathematicalprogramming to the mesh optimization. |

| Keywords: | parameter iteration method nonlinear duffing equation higher accuracy solution |
