Methods for quasi-Newton approximation. If the second
derivatives are approximated by Ipopt, it is better to do this only in the space of nonlinear variables. The following methods are call by Ipopt if the quasi-Newton approximation is selected. If -1 is returned as number of nonlinear variables, Ipopt assumes that all variables are nonlinear. Otherwise, it calls get_list_of_nonlinear_variables with an array into which the indices of the nonlinear variables should be written - the array has the lengths num_nonlin_vars, which is identical with the return value of get_number_of_nonlinear_variables(). It is assumed that the indices are counted starting with 1 in the FORTRAN_STYLE, and 0 for the C_STYLE.

Detailed Description

Base class for all NLP's that use standard triplet matrix form and dense vectors.

This is the standard base class for all NLP's that use the standard triplet matrix form (as for Harwell routines) and dense vectors. The class TNLPAdapter then converts this interface to an interface that can be used directly by ipopt.

This interface presents the problem form:

min f(x)

s.t. gL <= g(x) <= gU

 xL <=  x   <= xU

In order to specify an equality constraint, set gL_i = gU_i = rhs. The value that indicates "infinity" for the bounds (i.e. the variable or constraint has no lower bound (-infinity) or upper bound (+infinity)) is set through the option nlp_lower_bound_inf and nlp_upper_bound_inf. To indicate that a variable has no upper or lower bound, set the bound to -ipopt_inf or +ipopt_inf respectively

This method is called just before finalize_solution.

With this method, the algorithm returns any metadata collected during its run, including the metadata provided by the user with the above get_var_con_metadata. Each metadata can be of type string, integer, and numeric. It can be associated to either the variables or the constraints. The metadata that was associated with the primal variable vector is stored in var_..._md. The metadata associated with the constraint multipliers is stored in con_..._md. The metadata associated with the bound multipliers is stored in var_..._md, with the suffixes "_z_L", and "_z_U", denoting lower and upper bounds.
