getValue() cplex C++

Question

Actually, I'm a beginner on using cplex on C++. I try to stock the values of a variable (IloIntVarArray) after solving the MIP on a vector that I've put as an argument of the function by getValue(), but it doesn't work. Any suggestions?

Answer 1

Here's an example

IloNumArray values(getEnv());
getValues(values, _x);
for (int i = 0; i < _graph->GetArcCount(); i++)
{
    ClassOfArcs* arc = _graph->GetArc(i);
    arc->value = (double)values[arc->index];
}
values.clear();

Where x is an IloNumVarArray holding the value of variable x_ij (going from customer i to j). In the example, I wish to store the values of x in an std::vector _x.

Don't forget to do a value.end() when you finish passing all other variables in your model to avoid memory leaks.
