Can someone please check if gurobi solves the following model in a reasonable time?https://drive.google.com/file/d/1EraE4nnpC1bIUomcI8waVVKmjIdHAMim/view?pli=1Is there an online service, where I ca...

How do I optimize it efficiently? Gurobi treats it as a standard LP (runs barrier/simplex). Update: I'm not sure about my expectation anymore. The problem is min c'x s.t. Ax=b. The KKT system is un...

It seems that the site remembers my login only for a day and requests it afterwards. Said login go smoothly when I reply to a message, and I need to do it a couple of times until it "gets me." The ...

Is it possible, or do I need c++ for that? https://www.gurobi.com/documentation/9.5/refman/lpwarmstart.html    

How do I translate matlab's example linprog.m into c++? Specifically, translate     model.A = A;   model.obj = c;   model.modelsense = 'Min';   model.rhs = b;   model.sense = [ '<' ];    gurob...

I have a large linear program that takes 10 seconds, which is too long. I'd like to limit it and get a solution that is feasible but not necessarily optimal. For a mix-int problem, there's the para...

Can you venture an opinion on the following: Methods for binary linear programming - Mathematics Stack Exchangehttps://math.stackexchange.com/questions/4504572/methods-for-binary-linear-programming

Can you perhaps refer me to a paper that explains the algorithm? Usually, it seems to do a good job. Sometimes, though, the number of int vars increases for reducing bin vars or continuous vars. In...

hi, The pre-solve seems to be buggy: https://github.com/yalmip/YALMIP/discussions/986 -z

I have an MILP (mixed int linear prog). There is the comiso library https://www.graphics.rwth-aachen.de/software/comiso/ which does something super naive: Solve the problem treating all vars as co...
