Status key Interpretation
UN Unknown status
BS Is basic
SB Is superbasic
LL Is at the lower limit (bound)
UL Is at the upper limit (bound)
EQ Lower limit is identical to upper limit
** Is infeasible i.e. the lower limit is
greater than the upper limit.
Table 17.1: Status keys.
statuses are shown. In this case the information shows that the problem is primal and dual
feasible and the solution is optimal. Next the primal and dual objective values are displayed.
CONSTRAINTS
Subsequently in the constraint section the following information is listed for each constraint:
INDEX
NAME
AT
A sequential index assigned to the constraint by MOSEK
The name of the constraint assigned by the user.
The status of the constraint. In Table 17.1 the possible values of the status keys and their
interpretation are shown.
ACTIVITY
Given the i th constraint on the form
l c i ≤
n∑
a ij x j ≤ u c i, (17.1)
j=1
then activity denote the quantity ∑ n
j=1 a ijx ∗ j , where x∗ is the value for the x solution.
LOWER LIMIT
Is the quantity l c i
UPPER LIMIT
Is the quantity u c i
DUAL LOWER
(see (17.1)).
(see (17.1)).
Is the dual multiplier corresponding to the lower limit on the constraint.
DUAL UPPER
Is the dual multiplier corresponding to the upper limit on the constraint.
