Minimize number of optional intervals

  • 1.  Minimize number of optional intervals

    Hi Everyone,

    I'm looking for a way to determine which optional intervals are present in a solution and minimize this value.
    As far as I can tell both interval.isPresent() and model.isPresent(interval) do not seem to do what I intend.


    How can I write a constraint to minimize the number of optional intervals from a given array that appear in the final solution?

    Thank you,

    Adam

    you can add an objective IloMinimize on a summing expression on the IloPresenceOf(interval[i]) for all your interval[i].
