I use set_start_value function in Gurobi's Julia interface to set initial values for variables before solving the model. I did not see any change in the iteration behavior. To be more specific, I a...

Hello: I set the MIPgap to be 1% as follows (using julia):m_l = Model(with_optimizer(Gurobi.Optimizer,MIPGap=1e-2)). However, when I check the log, gurobi solved the problem to within 0.01%.I wish ...

I am running two MIP models using Gurobi, I call them A and B. B is the relaxed problem of A, and B has fewer variables, fewer constraints, fewer nonzeros, and fewer rows than A. Is that possible t...
