Detailed Description

Global properties.

This file contains global properties shared by all components of Lurupa. It contains possible return values and parameters of methods as enums or defines for enhanced readibility as well as string arrays with textual descriptions of some of these for displaying.

Enumeration Type Documentation

enum Bound_status

Bound status

The possible status values of a bound computation.

Enumerator:

bs_verified	Bound successfully computed
bs_priminf	Bound successfully computed; problem is verified to be infeasible
bs_dualinf	Bound successfully computed; problem is verified to be unbounded
bs_orginf	Bound not computed; the lp-solver claims infeasibility
bs_orgunb	Bound not computed; the lp-solver claims unboundedness
bs_pertinf	Bound not computed; a perturbed problem seems to be infeasible and inflation is not set
bs_noenc	Bound not computed; no enclosure of the solution set of linear system could be found
bs_warn	Bound not computed; the lp-solver gave a warning while solving a perturbed problem
bs_rank	Bound not computed; the equation matrix has not full rank
bs_iter	Bound not computed; the maximum number of iterations is exceeded
bs_failure	Bound not computed; an unexpected error occured
bs_timeout	Bound not computed; the lp-solver timed out solving a perturbed problem
bs_running	Bound computation in progress

enum Csv_style

CSV style.

The style which is used to save csv files in Report::write_vector and Report::write_matrix

Enumerator:

octave	Octave style; one file (problem_name.csv) with dimension and name as meta information
matlab	Matlab style; all variables in different files without dimension in one directory (problem_name)

enum Solver_status

Lp-solver status.

The possible status values returned by lp-solvers.

Enumerator:

ss_feasible	Lp-solver judges model to be feasible
ss_unbounded	Lp-solver judges model to be unbounded
ss_infeasible	Lp-solver judges model to be infeasible
ss_failure	Lp-solver returned from solving with a failure
ss_timeout	Lp-solver timed out solving
ss_unknown	Lp-solver status not yet known

enum Write_mps

Write lps as MPS file.

Which intermediate lps are written as MPS files to disk.

Enumerator:

wm_all	All intermediate lps.
wm_ask	Ask for all intermediate lps.
wm_none	No intermedate lp.
