WebMar 28, 2024 · The problem solved in the restoration phase is minimizing the constraint violation of the original NLP. Thus, the objective value 0.386285 displayed here is the norm of the constraint violation in the original NLP. Since this is larger than some threshold, the problem is concluded by the (locally) infeasible:
