    Yes, I did. It seems to work better without the reformulation.

    On Paramter Tuning with Callbacks

    Answered

    Is it possible to perform parameter tuning on a MIP model in which lazy constraints are added using callback?

  • Ankit Bansal commented,

    Thank you very much for your help. I am trying to solve a MIP model using Gurobi for my research that has a bunch of SOS1 constraints. I think SOS1 branching may be more effective for my model than...

  • Ankit Bansal commented,

    Yes. This answers my question. Thank you very much. What I meant by GUB branching can be found in the following IJOC paper (Section 2.2): https://pubsonline.informs.org/doi/abs/10.1287/ijoc.11.2.17...

  • Ankit Bansal commented,

    Thank you very much for your reply.  Couple of follow-up questions: how are they included in the branching? Is it through GUB branching or through some other method?

    On PreSOS1BigM Parameter

    Answered

    Consider a bunch of constraints of type \sum_{i\in N} x_{i} = 1, x_{i} \in {0,1}. If I model them as SOS1 constraints and set the PreSOS1BigM parameter equal to 0, will GUROBI perform GUB branching...
