How to use MinRel heuristic directly after root relaxation?

    Hi Cebajel,

    Have you tried explicitly setting the number of nodes explored by the MinRel heuristic with the MinRelNodes parameter? This heuristic is only applied at the end of the root node, but triggering it explicitly with the parameter might help.

    Best regards,

    Elisabeth

    You can also try other heuristics such as:

    They might also be effective for your problem.

    Cheers,

    Thanks Elisabeth and David!

    MinRelNodes accomplished the task. And I tried NoRelHeurTime and ZeroObjNodes but it didn't helped in reducing the runtime. PumpPasses is yet to try. But I am in a lot better position now. 
    Thanks.
