Nonlinear Curve-Fitting in the L , and LM Norms

In extending the Levenberg-Marquardt L2 method for nonlinear curve-fitting to the ¿j and L^ norms, the following problems arise, but are dealt with successfully: (1) Trial parameters are generated by linear programming, which can be timeconsuming. (2) Trial parameters are not uniquely specified in some cases. (3) There are intervals of the search parameter… (More)
