    Hi Thomas,

    That is an interesting question.
    We don't find many cases where this heuristic is useful so right now there's no way to control the number of threads used for it. I can imagine that using more threads than the number of partitions may be useful in cases for example with less and larger partitions e.g. the whole set of variables into 2 partitions.

    Have you found this heuristic to be useful for your problem? If so, we can look into whether this would help.

    Cheers, 
    David

    Hi David,

    I redeveloped/improved my optimization modell. In the past I saw improvements with the heuristic, but actually gurobi does not even start the heuristic although I set PartitionPlace to 31.

    Actually there are other problems in my model - I  will come back to your offer of help later.

    Best regards

    Thomas
