Verification of the objective gradients.
----------------------------------------
All objective gradient elements have been set.
Simple Check:
The Jacobian seems to be ok.
The largest relative error was 1.04e-08 in subfunction 3
Verification of the constraint gradients.
-----------------------------------------
All constraint gradient elements have been set.
Simple Check:
The Jacobian seems to be ok.
The largest relative error was 1.91e-08 in constraint 1
