get_problem_sizes

returns properties of a decoded SIF problem

Calling Sequence

props=get_problem_sizes(probpath)

Parameters

probpath

The path of the directory where the decoded problem files have been stored by sifdecode

props

A tlist with the following fields:

name

a character string, the problem name

nfree

a number with integer value: the number of free variables

nfixed

a number with integer value: the number of fixed variables (variables which have imposed values).

nlower

a number with integer value: the number of lower bounded variables.

nupper

a number with integer value: the number of upper bounded variables.

nboth

a number with integer value: the number of lower AND upper bounded variables.

nslack

a number with integer value: the number of

nlinobj

a number with integer value: the number of variables which contribute linearily to the objective

nnlinobj

a number with integer value: the number of variables which contribute non-linearily to the objective

nlineq

a number with integer value: the number of linear equality constraints

nnlineq

a number with integer value: the number of nonlinear equality constraints

nlinin

nnlinin

a number with integer value: the number of nonlinear inequality constraints

Description

Given a decoded SIF problem stored in file probpath directory , this function reads the data stored in the OUTSDIF.d file to get the problem sizes.
