General-purpose optimization


General-purpose optimization based on Nelder–Mead, quasi-Newton, conjugate-gradient and simulated annealing algorithms. The following parameters are available for fine tuning of the algorithm selected:
Conjugate gradient
Simulated annealing
The resulting analysis is the following:(blue points are representing lowest values, red ones are highest values)
