java.lang.Objectilog.cplex.IloCplex.Quality
Objects of this class contain information computed to measure the quality of a solution.
The possible quality
measures are declared in IloCplex.QualityType
. A quality
object is returned by the method IloCplex.getQuality
. The
returned quality object contains its type and the numeric value
of the requested quality measure. For many quality measures, the
value is attained at a specific constraint or variable. In such cases,
the relevant constraint or variable is contained in the quality
object as well, unless the constraint has been implicitly created
as a result of automatic linearization.
Methods are provided to query all information stored in a quality object.
