Dual Solution Information
When solving an LP or QP, all the algorithms also compute dual solution information that can be queried. Reduced costs can be accessed by calling the method IloCplex.getReducedCost() or IloCplex.getReducedCosts(). Similarly, dual solution values for the ranged constraints of the active model can be queried using methods IloCplex.getDual() or IloCplex.getDuals().
