Dear all,

In what way should I extract the actual values of the expressions of a solved problem?

Thank you in advance,

To get the values of variables, use IloCplex::getValue or IloCplex::getValues.

To get the value of the expression in a constraint, I would probably use IloCplex::getSlack or IloCplex::getSlacks (and then use the difference between the slack and the upper limit of the constraint to get the value.

Although I've never tried it, I think you can use IloCplex::getValue to get the value of any IloNumExpr instance (including the expression in a constraint), since IloNumExpr is a subclass of IloNumExprArg and there's a version of getValue that takes an IloNumExprArg argument. There does not seem to be an array version (getValues), though, so to get values for an array of expressions you'd presumably have to loop through the array.

Ha thx!

There is just no getValues() for the whole array of expressions. I'm now using your tip about getValue() in a for-loop.
