3. Is it possible to retrieve the best (lower) bound of a MILP problem that did not reach the optimal solution?

I have just found how to do it using a callback. You have to use if (where ==GRB_CB_MIPNODE && getIntInfo(GRB_CB_MIPNODE_STATUS) == GRB_OPTIMAL) to find out if the node is optimal for the LR of th...
