Many thanks Riley for the very useful info. Best, Marilena  

Hi again, and Happy New Year!I have a follow-up question on this issue. Communication with Julia developers indicated that as long as a feasible solution is available at the time of early terminati...

Indeed, I can retrieve the values I need with MOI.get(grb, Gurobi.VariableAttribute("X"), index(my_x))Therefore, if I attempt to explain what is happening is that the solution is there from Gurobi,...

Hi Riley, Gurobi version is 11.0.2. I am using Julia v1.9.3 and JuMP v1.23.2 with the Gurobi.jl wrapper v1.3.1.Below you can see the gurobi log for a test case where I am setting a time limit of 4....

Great, thanks again. Marilena 

Hi Riley, and thanks for your answer.Could you please clarify, does this mean that the answer to my original question - retrieving duals during branch and bound - is “No, it is not possible”?If it ...

I have performed further tests with a Bender's decomposition algorithm with feasibility cuts (thus, with occasions that the slave problems are infeasible) and I have made some observations, the rea...

Dear Riley, Thank you very much for your answer! Indeed, you are right. With presolve on I can still retrieve the information I need. You are also right in that I can use the concurrent method and ...

Thank you Dan for your reply, In this case I have a follow-up question related to distributed applications. I solve a number of those LPs in a distributed manner. In my local computer (therefore, t...
