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 |

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.
