Yes, you can do this. Just have a look at the following links: https://www.gurobi.com/documentation/9.0/refman/vbasis.html https://www.gurobi.com/documentation/9.0/refman/cbasis.html https://www....

1. The returned vector is the Farkas Dual of the problem where it is returned from. (Obviously.) 2./3. Do you have variables with non-trivial bounds? If yes, please read this (including the comment...

I would hope that the preprocessor is able to detect two corresponding constraints and make a ranged constraint out of them. From a linear point of view, if I knew there is a ranged constraint, I w...

Do both processors have the same single-core performance (base frequency/turbo frequency)?
-
Hmm, I guess only someone who knows internals of Gurobi can give an adequate answer. I do not really expect such a behaviour. Does this also happen if you set DualReductions (and maybe PreDual) to ...

Hi Robert, did you read the article that Greg mentioned? Gurobi solves a mathematical program. In this mathematical program, 9.70E-12 is a solution that is considered integer feasible. A mathematic...

I fully agree that this is dangerous and Gurobi should not do the rounding, but in the end, one needs a decision. True or false, 1 or 0 (not 9.7e-12 * true). Your article also says: "Our recommenda...

9.70E-12 means 9.7 * 10^-12 which is 0.0000000000097. So you should better assume 0 instead of 1 :-) Just round the values you receive.

Ah, I see. You are calling: r.RCs.RCz.RC I guess, this should be something like: r.getAttr(GRB.Attr.RC)s.getAttr(GRB.Attr.RC)z.getAttr(GRB.Attr.RC)
