WebThe value corresponding to each key is the respective infeasibility. Infeasibility is defined as the distance between the primal value of the constraint (see MOI.ConstraintPrimal) and the nearest point by Euclidean distance in the corresponding set. Notes.

I have tried to use opti.debug.show_infeasibilities() - but it outputs many instabilities with small violations. I have indeed verified that the subject_to(cost<1e-3) violation is around 0.4 - I guess that could be a critical point. I tried just including the cost in the objective but it will not get minimized to the desired level of complementarity constraints.
