Infeasibility removes by additional constraints like 13 +x 15 23 +x NettetDocuments facilities for evaluating solution quality in LP models. Infeasibility and unboundedness in linear programs are closely related. (For more about that idea, see the topics in Infeasibility and unboundedness.)When the linear program CPLEX solves is infeasible, the associated dual linear program has an unbounded ray. Similarly, when …

NettetIf an infeasibility is detected, it is possible to trace this back and uncover the cause of it. This diagnosis is carried out whenever the control parameter TRACE is set to 1 before the optimization routine XPRSmaxim ( MAXIM) or XPRSminim ( MINIM) is called. In such a situation, the cause of the infeasibility is then reported as part of the ...

The optimization status that is returned should be either INFEASIBLE or UNBOUNDED.
