280 CHAPTER 13. THE MPS FILE FORMAT
MIN
MINIMIZE
MAX
MAXIMIZE
It should be obvious what the implication is of each of these four lines.
13.1.4 OBJNAME (optional)
This is an optional section that can be used to specify the name of the row that is used as objective
function. The OBJNAME section contains one line at most which has the form
objname
objname should be a valid row name.
13.1.5 ROWS
A record in the ROWS section has the form
? [cname1]
where the requirements for the fields are as follows:
Field Starting Maximum Re- Description
position width quired
? 2 1 Yes Constraint key
[cname1] 5 8 Yes Constraint name
Hence, in this section each constraint is assigned an unique name denoted by [cname1]. Please note
that [cname1] starts in position 5 and the field can be at most 8 characters wide. An initial key (?)
must be present to specify the type of the constraint. The key can have the values E, G, L, or N with
the following interpretation:
Constraint
type
li c u c i
E finite li
c
G finite ∞
L −∞ finite
N −∞ ∞
In the MPS format an objective vector is not specified explicitly, but one of the constraints having the
key N will be used as the objective vector c . In general, if multiple N type constraints are specified,
then the first will be used as the objective vector c .
13.1.6 COLUMNS
In this section the elements of A are specified using one or more records having the form
