Verification of the objective gradients.
----------------------------------------
The user sets 0 out of 4 objective gradient elements.
Each iteration 4 gradient elements will be estimated numerically.
Verification of the constraint gradients.
-----------------------------------------
The user sets 3 out of 8 constraint gradient elements.
Each iteration, 5 gradient elements will be estimated numerically.
Simple Check:
The Jacobian seems to be ok.
The largest relative error was 5.22e-09 in constraint 1
Finite difference intervals.
