592 APPENDIX F. MOSEK FILE FORMATS Field Starting Maximum Re- Description position width quired [name] 5 8 Yes Name of the RHS vector [cname1] 15 8 Yes Constraint name [value1] 25 12 Yes Numerical value [cname2] 40 8 No Constraint name [value2] 50 12 No Numerical value The interpretation of a record is that [name] is the name of the RHS vector to be specified. In general, several vectors can be specified. [cname1] denotes a constraint name previously specified in the ROWS section. Now, assume that this name has been assigned to the i th constraint and v 1 denotes the value specified by [value1], then the interpretation of v 1 is: Constraint type li c u c i E v 1 v 1 G v 1 L v 1 N An optional second element is specified by [cname2] and [value2] and is interpreted in the same way. Please note that it is not necessary to specify zero elements, because elements are assumed to be zero. F.1.1.8 RANGES (optional) A record in this section has the form [name] [cname1] [value1] [cname2] [value2] where the requirements for each fields are as follows: Field Starting Maximum Re- Description position width quired [name] 5 8 Yes Name of the RANGE vector [cname1] 15 8 Yes Constraint name [value1] 25 12 Yes Numerical value [cname2] 40 8 No Constraint name [value2] 50 12 No Numerical value The records in this section are used to modify the bound vectors for the constraints, i.e. the values in l c and u c . A record has the following interpretation: [name] is the name of the RANGE vector and [cname1] is a valid constraint name. Assume that [cname1] is assigned to the i th constraint and let v 1 be the value specified by [value1], then a record has the interpretation:
F.1. THE MPS FILE FORMAT 593 Constraint Sign of v 1 l c i u c i type E - u c i + v 1 E + l c i + v 1 G - or + l c i + |v 1| L - or + u c i − |v 1| N F.1.1.9 QSECTION (optional) Within the QSECTION the label [cname1] must be a constraint name previously specified in the ROWS section. The label [cname1] denotes the constraint to which the quadratic term belongs. A record in the QSECTION has the form [vname1] [vname2] [value1] [vname3] [value2] where the requirements for each field are: Field Starting Maximum Re- Description position width quired [vname1] 5 8 Yes Variable name [vname2] 15 8 Yes Variable name [value1] 25 12 Yes Numerical value [vname3] 40 8 No Variable name [value2] 50 12 No Numerical value A record specifies one or two elements in the lower triangular part of the Q i matrix where [cname1] specifies the i . Hence, if the names [vname1] and [vname2] have been assigned to the k th and j th variable, then Q i kj is assigned the value given by [value1] An optional second element is specified in the same way by the fields [vname1], [vname3], and [value2]. The example minimize − x 2 + 0.5(2x 2 1 − 2x 1 x 3 + 0.2x 2 2 + 2x 2 3) subject to x 1 + x 2 + x 3 ≥ 1, x ≥ 0 has the following MPS file representation * File: qo1.mps NAME qo1 ROWS N obj G c1 COLUMNS x1 c1 1.0 x2 obj -1.0 x2 c1 1.0 x3 c1 1.0 RHS rhs c1 1.0
