Recently, I have a problem when using callback in a MIP problem.
In the condtion "where == GRB_CB_MIPNODE" and "getIntInfo(GRB_CB_MIPNODE_STATUS) == GRB_OPTIMAL", I construct a better feasible solution and pass it to Gurobi by function "setSolution". However, it seems that Gurobi does not know the feasible solution.
I use the branch and cut schema. Is it possible that my REAL feasible solution is not as good as the "current-feasible" solution obtained by Gurobi? Since some cuts have not been added to Gurobi.
