Detailed Description

NLP node implementation subclass for preprocessing and basis manipulation.

This is an implementation node class that takes an original NLP and transforms it by:

Original NLP formulation

The original NLP (as specified by the subclass) takes the form:

    min    f_orig(x_orig)
    s.t.   c_orig(x_orig) = 0
           hl_orig <= h(x_orig) <= hu_orig
           xl_orig <= x_orig <= xu_orig
 where:
         x_orig         <: REAL^n_orig
         f_orig(x_orig) <: REAL^n_orig -> REAL
         c_orig(x_orig) <: REAL^n_orig -> REAL^m_orig
         h_orig(x_orig) <: REAL^n_orig -> REAL^mI_orig

Conversion of general inequalities to equalities using slack variables

The original NLP formulation above is transformed by adding slack variables s_orig <: REAL^mI_orig, defining a new x_full = [ x_orig; s_orig ] and forming the new NLP:

    min    f_full(x_full)
    s.t.   c_full(x_full) = 0
           xl_full <= x_full <= xu_full

 where:

         x_full           = [ x_orig ]  n_orig
                            [ s_orig ]  mI_orig

         f_full(x_full)   = f_orig(x_orig)

         c_full(x_full)   = [ c_orig(x_orig)          ]  m_orig
                            [ h_orig(x_orig) - s_orig ]  mI_orig

         xl_full          = [ xl_orig ]  n_orig
                            [ hl_orig ]  mI_orig

         xu_full          = [ xu_orig ]  n_orig
                            [ hu_orig ]  mI_orig

Note that in this case, the Jacobian of the new equality constraints and the gradient of the new objective become:

   Gc_full = [  Gc_orig    Gh_orig   ]  n_orig
             [     0          -I     ]  mI_orig

                 m_orig     mI_orig

   Gf_full = [ Gf_orig ]  n_orig
             [    0    ]  mI_orig

It is up to the subclass to implement imp_calc_Gc() and imp_calc_Gh() in a way that is consistent with the above transformation while also considering basis permutations (see NLPSerialPreprocessExplJac). As for the gradient Gc_full, the subclass can actually include terms for the slack variables in the objective function but the most common behavior will be to just ignore slack variables in the subclass.

Preprocessing and basis manipulation

The initial basis selection is the original order (x_full = [ x_orig; s_orig ]) with the variables fixed by bounds being removed, and assumes there are no dependent equations (r == m).

The implementations of the Jacobian matrices Gc and Gh are not determined here and must be defined by an NLP subclass (see NLPSerialPreprocessExplJac for example).

This class stores the variable permutations and processing information in two parts. In the first state, the fixed variables are removed as:

   var_remove_fixed_to_full =  [ not fixed by bounds |  fixed by bounds  ]
                               [1 ..                n|n+1 ..        n_full]

The mapping i_full = var_remove_fixed_to_full()(i_free_fixed) gives the index of the original variable (i_full) for the sets of variables not fixed and fixed by bounds.

The inverse mapping i_free_fixed = var_full_to_remove_fixed()(i_full) can be used to determine if a variable is fixed by bounds or not..

On top of this partitioning of free and fixed variables, there is a second stage which is a permutation of the free variables into dependent and independent sets that is needed by the client.

   var_perm = [ dependent variables | independent variables ]
              [1..               n-r|n-r+1...              n]

The mapping i_free_fixed = var_perm()(i_perm) is used to determine the index of a free variable in var_remove_fixed_to_full() given its index (i_perm) for the current basis selection.

For example, if x is the vector of variables for the current basis selection and x_full is the vector of variables in the original order including the fixed variables then the following is true:

x(i) == x_full(var_remove_fixed_to_full()(var_perm()(i))), for i = 1...n

The permutation equ_perm() gives the partitioning of the equality constraints into decomposed and undecomposed equalities. Decomposed inequality constraints are not supported currently.

Subclass developers notes

Handling of multiple updates by subclasses: Here we discuss the protocol for the handling of multiple updates to quantities during the calculation of other quantities. In order to simplify the implementation of subclasses as much as possible, storage for all iteration quantities will be passed to the subclass in the methods imp_calc_f_orig(), imp_calc_c_orig(), imp_calc_h_orig() and imp_calc_Gf_orig() regardless of what quantities where set by the user in the NLP interface. The subclass can always find out what was set by the client by calling get_f(), get_c(), get_Gf() etc. Therefore, in general, clients should just only compute what is required in each call to imp_calc_xxx_orig() and only update other quantities if it is absolutely free to do so (e.g. computing a function value when a gradient is computed using AD) or is required to do so (e.g.an external interface that forces both f_orig(x_orig), c_orig(x_orig) and h_orig(x_orig) be computed at the same time). It is up to the subclass to remember when a quantity has already been computed so that it will not be computed again unnecessarily. It is always safe for the subclass to ignore these issues and just do what is easiest. More careful implementations can be handled by the subclass by keeping track of get_xxx() and newx and remembering when quantities are computed.

The following methods from the NLP interface must be overridden by the NLP subclass: max_var_bounds_viol(), set_multi_calc(), multi_calc().

The following methods from the NLPVarReductPerm interface must be overridden by the NLP subclass: nlp_selects_basis().

In addition, the methods from this interface that must be overridden are: imp_n_orig(), imp_m_orig(), imp_mI_orig(), imp_xinit_orig(), imp_has_var_bounds(), imp_xl_orig(), imp_xu_orig(), imp_hl_orig(), imp_hu_orig(), imp_calc_f_orig(), imp_calc_c_orig(), imp_calc_h_orig() and imp_calc_Gf_orig().

The NLP method initialize() should also be overridden by all of the subclasses (and call initialize() on its direct subclass).

The following methods (with default implementations) may also be overridden by a subclass: imp_get_next_basis() and imp_report_orig_final_solution().

The default implementation of this function is to call the method imp_report_full_final_solution(x_full,lambda_full,nu_full). This function translates from x, lambda and nu into the original order with fixed variables added back to form x_full, lambda_full, lambdaI_full and nu_full.

protectedvirtual

Return the next basis selection (default returns false).

Parameters
var_perm_fullout. Contains the variable permutations (including slack variables possibly).
equ_perm_full[out] (size = m_orig + mI_orig)). Contains the constriant permutations (including general inequalities possibly).
rank_full[out] Returns the rank of the basis before fixed variables are taken out of var_perm_full and equ_perm.
rank[out] Returns the rank of the basis after fixed variables are taken out of var_perm_full and equ_perm. If there are no fixed variables then rank should be equal to rank_full.

Postconditions:

  • [return == true] var_perm_full(i) < var_perm_full(i+1), for i = 1...rank_full-1
  • [return == true] var_perm_full(i) < var_perm_full(i+1), for i = rank_full...n_full-1
  • [return == true] equ_perm_full(i) < equ_perm_full(i+1), for i = 1...rank-1
  • [return == true] equ_perm_full(i) < equ_perm_full(i+1), for i = rank...m_full-1

This method will only be called if this->nlp_selects_basis() == true.

The basis returned by the subclass must be sorted var_perm_full = [ dep | indep ] and equ_perm_full = [ equ_decomp | equ_undecomp ]. The subclass should not remove the variables fixed by bounds from var_perm_full as they will be removed by this class as they are translated. In addition, the subclass can also include slack variables in the basis (if mI_orig > 0>/tt>). Therefore, a nonsingular basis before fixed variables are removed may not be nonsingular once the fixed variables are removed. During the translation of var_perm_perm, the variables fixed by bounds are removed by compacting var_perm_full and adjusting the remaining indices. For this to be correct with variables fixed by bounds, it is assumed that the subclass knows which variables are fixed by bounds and can construct var_perm_full so that after the translated the basis will be nonsingular. The first rank entries in var_perm_full[1:rank_full] left after the fixed variables have been removed give the indices of the dependent (basic) variables and the remaining variables in var_perm_full[rank_full+1,n_full] are the indices for the independent (nonbasic) variables. To simplify things, it would be wise for the NLP subclass not to put fixed variables in the basis since this will greatly simplify selecting a nonsingular basis.

The first time this method is called, the subclass should return the first suggested basis selection (even if it happens to be identical to the original ordering).

The default implementation returns false which implies that the NLP subclass has no idea what a good basis selection should be..

To be overridden by subclasses to report the final solution in the original ordering natural to the subclass.

Note that the lagrange multipliers for fixed variables that have been preprocessed out of the problem are not computed by the optimization algorithm and are therefore not available. These multipliers are designated with the special value fixed_var_mult() but the numerical value is not significant.

The default implementation of this function is to do nothing.
