I would like to know how origin try to optimize the different parameters during a fitting routine. I mean if I have three parameters like P1, P2 and P3. Origin tries to optimize P1 first and P2 and then P3. No ? If this is right, it means that the order of the parameters in my routine is important. No ?
Origin uses the Levenberg-Marquardt minimization algorithm in NLSF (this is the default method - we also offer Simplex), and this algorithm is not sensitive to the order of the parameters. The minimization involves all parameters - it does not minimize with respect to P1, then P2, then P3 etc.
