I am still a bit unsure that I understand exatly what you are doing.If I understand correctly, you give Gurobi a partial start (for example by using a MST file). You increase the StartNodeLimit par...

Thank you Jaromił,> By a "convex-quadratic" variable, we mean a variable that participates only in linear and convex-quadratic constraints.I did not define it properly, but you seem to have gotten ...

When you mention that the solution generated by warm starting has a large optimality gap, are you referring to the intermediate output from Gurobi while it is running, or is this based on a test ca...

A cutting-plane approach can be quite beneficial in certain scenarios. This method involves iteratively formulating Mixed-Integer Linear Programs (MILPs) and solving them using tools like Gurobi. W...

I think you will have to specifiy which kind of optimization problem your are solving with Gurobi.LP,QP, MILP, QCQP or nonconvex MINLP. Also, you will have to specify if you are interested in worst...

How does Gurobi handle 'convex-quadratic' variables in nonconvex optimization?
回答済みI am planning to implement an algorithm that solves multiple subproblems of the form \[\begin{align} \underset{\boldsymbol{x},\boldsymbol{y}^i,\boldsymbol{z}^i,t}{\min} &&f(\boldsymbol{x}) & \\ \te...

Hi Jaromił, thanks for your suggestion. Indeed, this is very similar to the workaround currently employed. As you pointed out, you could always check for more special cases. Personally, I would arg...

Detect linear problem
回答済みI add constraints to my model within the C++ API automatically based on user input. I do not know in advance if the constraint given by the user will be linear or quadratic. At the moment I will j...

Help with Unbounded or Infeasible
回答済みI have the following problem with the C++ API. My understanding is that the following code: #include <iostream> #include <limits> #include "gurobi_c++.h" int main() { // construct model ...
