    Hi Taner,

    I guess you are using 8.1.1? If so, from what you explain this seems a bit odd, maybe you can share a minimal example where I can reproduce this? If you can, contact me directly at espinoza at gurobi dot com

    Hi, Taner,

    Your description is quite clear. I have got the same question as you. I also tried my best to solve this problem. But unfortunately, it did not work. 

    So have your question been solved? Many thanks for any experience shared.

    Just out of curiosity, has the problem been finally solved? (I encountered the same message and googling brought me here. However, I don't know if I have the same issue - it may be just mistakes on my input :) )

    @Yauhen, it was all my bad. My solution was not really feasible. I thought it was a feasible solution and was wrong. Thanks to Daniel, I could verify it.

    Thanks, Taner Cokyasar. It seems I might have also a mistaken initial feasible solution. I wonder if there is a way to check the solution I set as start. Ideally, is it possible to see which constraints my provided start solution does NOT satisfy?..

    Okay, I perhaps better post it as a separate question as it might be useful for other users too.
