| Abstract: | In order to reduce nodes of the approximate cubic spline function in the given average deviatton, lot of global and local algorithms have been developed, The global algorithm deduces a good methed for producing the least number of nodes, and the local algorithm can both save caculation time and achieve satisfactory result. |
