The drop down box "method.modFit" makes it possible to choose between the optimisation -algorithms "Marq" (the default Levenberg-Marquardt implementation from the R package -`minpack.lm`), "Port" (an alternative, also local optimisation algorithm) and -"SANN" (the simulated annealing method - robust but inefficient and without a -convergence criterion). +algorithms "Port" (the default in mkin versions > 0.9-33, a local optimisation +algorithm using a model/trust region approach), "Marq" (the former default in +mkin, a Levenberg-Marquardt variant from the R package `minpack.lm`), +and "SANN" (the simulated annealing method - robust but inefficient and without +a convergence criterion). Finally, the maximum number of iterations for the optimisation can be adapted using the "maxit.modFit" field. -- cgit v1.2.1
