Optimization performance
| Optimizer | Deviation | Correct pars. | Fun. calls | Limits |
|---|---|---|---|---|
| Levenberg–Marquardt | 1.0994 | 13/13 | 598 | 107 |
| Trust region | 1.0995 | 13/13 | 2184 | 107 |
| Simulated annealing | 12.62 | 12/13 | 10 323 | 400 |
| Direct search | 165807 | 5/13 | 7651 | 100 |
| Genetic algorithm | 188 | 3/13 | 40 000 | 103 |
Deviation of 1 corresponds to a perfect fit. Correctly determined parameters have a deviation below 30%. The required function calls are proportional to the fitting time. Limits around the true value are used during calibration stressing the high performance of the Levenberg–Marquardt and trust region optimizers.
