Is there a way to tell gurobi to stay at root node until a certain condition is met?
AnsweredI'm working on a MIP problem (minimization). Currently, I have an exponentially large family of constraints \(C\), which I separate dynamically by solving an auxiliary problem \(SP\) (for separatio...

Do lazy constraints cut fractional solutions?
AnsweredHere's a log of my model. I'm just working with the root node (node limit = 1) and have the heuristics parameter set to 0 as well as every gurobi cut (hence the lack of integer solutions) For the s...

Terminating optimization when leaving root node posts a different bestbound than the one in log.
Awaiting user inputPython 3 + Gurobi 9.5 I'm currently doing lower bound analysis in the root node. Since I'm only interested in the root I terminate the optimization using callbacks: if where == GRB.Callback.MIP and...

How does gurobi calculate the "Node Depth" number shown in logs?
AnsweredHi everyone, as the title says, I'm curious as how does gurobi get that number. Since, to the best of my knowledge (and this post https://support.gurobi.com/hc/en-us/community/posts/360047974992-Ge...
