Ah thanks so much for the fast reply and info on correct usage. It seems that I didn't understand the relationship between \(\texttt{env}\) and \(\texttt{model}\). Your snippet is now working for m...

GRB update environment
進行中I am solving an optimization problem `P := min f(x) : x in X` where `X` has many linear constraints. To speed up the process, I instead consider solving a sequence of problems of the form `P^i := m...

回答済みI am using julia, so my question might be more appropriate for the Gurobi.jl folks, but I was hoping to check here first to see if something is possible. I have an optimization `model` that is cu...

Thanks Mario! When I query this field for an LP solved with barrier, I find that I obtain an error (1005: DATA_NOT_AVAILABLE) though the optimal objective is nonzero and the solver terminates succe...

回答済みI am building an LP model with the C API that I know has more than 2 billion nonzeros, and I am wondering whether the best practice is to (1) initialize all of the variables and bounds with `GRBnew...

Retrieve relative gap and dual objective value
ユーザーの入力を待っています。I am running a barrier method to solve an LP and a QP and would like to retrieve final residuals: primal infeasibility, dual infeasibility, relative objective value gap final dual objective value ...
