Hi, Same issue here. To solve a MINLP, I run Gurobi's B&C on a MILP relaxation and, at each MIPSOL, I either cutoff the integer node with a combinatorial cut or provides the actual MINLP solution i...

And so I now have a feature request: tagged solutions to not to have to check their quality by ourselves ! Thank you very much Maliheh.

non LP-optimal heuristic integer solution at CB_MIPSOL
回答済みHi,I solve a MILP with my proper callback function:At a CB_MIPSOL event, a restricted problem is solved where all integer variables are fixed to their current values in the MILP solution.If the res...

Hi Elisabeth, thank you and indeed it was probably not clear, sorry. I try to explain below, but it is OK if there is no answer for now: it is more a wish for a feature, than a question. Just like...

回答済みHi, Gurobi will allow to set a feasible solution at a MIPSOL node, according to: https://support.gurobi.com/hc/en-us/community/posts/360067079431/comments/360014694792 But can we force this feasibl...
