Hi Sudheer, This is a very interesting topic.  A powerful property related to this is Total Unimodularity. See for example the resources: https://theory.stanford.edu/~jvondrak/MATH233B-2017/lec3.p...

Hi Cebajel, Have you tried explicitly setting the number of nodes explored by the MinRel heuristic with the MinRelNodes parameter? This heuristic is only applied at the end of the root node, but tr...

Hi Tam, Yes, steps 1. and 2. that you suggest are one way of writing a QUBO problem so that you can solve it with Gurobi. If you write your problem in this way, then you can for example use the Pyt...

Hi Nicolai, You can use Callbacks to do this. For this, you should query the RUNTIME at the "where" values that come before Gurobi enters the Branch-and-Bound (PRESOLVE, SIMPLEX, BARRIER). See Call...

Hi Mr. Truc, Please have a look at our Quick Start Guide section "Floating License" to find out how to set up a token server. Here are the links for Windows, Linux and MacOS: https://www.gurobi.c...

Hi Bin,  Please see my solution to your other post. If you only need these values when Gurobi finds a feasible solution, then you only have to query the attributes at the MIPSOL where value. (See C...

Hi Bin, You can query the current best objective, current best bound, and runtime using the OBJBST, OBJBND and RUNTIME Callback Codes. Here is an example Python code of how to query these attribute...

Hi Enis,  As discussed on the phone, and as my colleague Jaromił mentioned, Gurobi does not come with a Graphical User Interface. You mentioned that you only have to solve problems which are given ...
