594 APPENDIX F. MOSEK FILE FORMATS QSECTION obj x1 x1 2.0 x1 x3 -1.0 x2 x2 0.2 x3 x3 2.0 ENDATA Regarding the QSECTIONs please note that: • Only one QSECTION is allowed for each constraint. • The QSECTIONs can appear in an arbitrary order after the COLUMNS section. • All variable names occurring in the QSECTION must already be specified in the COLUMNS section. • All entries specified in a QSECTION are assumed to belong to the lower triangular part of the quadratic term of Q . F.1.1.10 BOUNDS (optional) In the BOUNDS section changes to the default bounds vectors l x and u x are specified. The default bounds vectors are l x = 0 and u x = ∞ . Moreover, it is possible to specify several sets of bound vectors. A record in this section has the form ?? [name] [vname1] [value1] where the requirements for each field are: Field Starting Maximum Re- Description position width quired ?? 2 2 Yes Bound key [name] 5 8 Yes Name of the BOUNDS vector [vname1] 15 8 Yes Variable name [value1] 25 12 No Numerical value Hence, a record in the BOUNDS section has the following interpretation: [name] is the name of the bound vector and [vname1] is the name of the variable which bounds are modified by the record. ?? and [value1] are used to modify the bound vectors according to the following table: ?? lj x u x j Made integer (added to J ) FR −∞ ∞ No FX v 1 v 1 No LO v 1 unchanged No MI −∞ unchanged No PL unchanged ∞ No UP unchanged v 1 No BV 0 1 Yes LI ⌈v 1 ⌉ unchanged Yes UI unchanged ⌊v 1 ⌋ Yes
F.1. THE MPS FILE FORMAT 595 v 1 is the value specified by [value1]. F.1.1.11 CSECTION (optional) The purpose of the CSECTION is to specify the constraint in (F.1). x ∈ C. It is assumed that C satisfies the following requirements. Let x t ∈ R nt , t = 1, . . . , k be vectors comprised of parts of the decision variables x so that each decision variable is a member of exactly one vector x t , for example Next define ⎡ x 1 = ⎣ x 1 x 4 x 7 where C t must have one of the following forms • R set: ⎤ ⎦ and x 2 = ⎡ ⎢ ⎣ x 6 x 5 x 3 x 2 ⎤ ⎥ ⎦ . C := { x ∈ R n : x t ∈ C t , t = 1, . . . , k } • Quadratic cone: C t = {x ∈ R nt }. ⎧ ⎨ C t = ⎩ x ∈ ∑ Rnt : x 1 ≥ √ nt j=2 x 2 j ⎫ ⎬ ⎭ . (F.2) • Rotated quadratic cone: ⎧ ⎨ C t = ⎩ x ∈ Rnt : 2x 1 x 2 ≥ ⎫ ∑n t ⎬ x 2 j, x 1 , x 2 ≥ 0 ⎭ . j=3 (F.3)
