>Solves the following parametric nonlinear program (NLP):min          F(x, p)
>x  subject to             LBX <=   x    <= UBX LBG <= G(x, p) <= UBG
>p  == P      nx: number of decision variables     ng: number of constraints
>np: number of parameters

>When in warmstart mode, output NLP_SOLVER_LAM_X may be used as input

>NOTE: Even when max_iter == 0, it is not guaranteed that
>input(NLP_SOLVER_X0) == output(NLP_SOLVER_X). Indeed if bounds on X or
