Class IloCplex.QualityType

java.lang.Object

ilog.cplex.IloCplex.QualityType

Enclosing class:

IloCplex

public abstract static class IloCplex.QualityType
extends java.lang.Object

This class contains symbolic names to identify measures of the quality of a solution. These measures can be queried from the method IloCplex.getQuality. These solution quality measures pertain either to characteristics of the computed solution or to the accuracy measures of the computed solution. When the name of the solution quality measure begins with Max, that measure identifies a constraint or a variable associated with the requested solution quality measure. For example, if you pass the solution quality measure MaxPi to the method IloCplex.getQuality, the result is an instance of IloRange with the largest dual value (that is, a characteristic of the solution) among the constraints in the model specified by the IloCplex object. Similarly, the solution quality measure MaxIntInfeas causes the method IloCplex.getQuality to return an instance of IloNumVar with the largest integrality violation (that is, a measure of accuracy) in the computed solution. For these solution quality measures, the variable or range returned is the first variable or range that attains the maximal associated quality value.
