Optimize solver

[1-Bart-1]

The FBDF solver has parameters that might not be optimal for a kite system. Create an optimizer that finds optimal values for best runtime performance.

If you reduce the accuracy, you can always improve the performance. You cannot automate the tradeoff. At least abstol and reltol must be defined in settings.yaml.

Yes I checked and there is not much more you can change for the FBDF solver. Had a different solver in mind I think...

Only thing that should be tested is the AutoFiniteDiff vs AutoForwardDiff performance.
