Hi Riley, Thanks much for getting back to me! I have developed a simple supply chain model that uses linear programming. To solve this problem, I specified the use of primal simplex. After obtain...

set the initial values of variables to warmstart
回答済み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...

Hi, Thanks for your response. "The MIPGap value refers to at least the gap value that Gurobi has to reach before declaring optimality" Does this mean that as long as I set MIPgap>=0.01% (default), ...

About the MIPgap
回答済み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 ...

About the memory usage
ユーザーの入力を待っています。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...
