Gurobi software now available for download

I am behind Erwin Kalvelagen, who writes an extremely useful blog where many challenging modeling problems are solved (this is one of my “must read” blogs), in announcing that Gurobi’s standalone software is now available.  I particularly like that the trial version is 500 variables and 500 constraints, which is large enough to see how the software really works, at least for MIP.  I had attended part of a software session at the recent INFORMS conference and left impressed both with the software and with Gurobi’s business plan.

    I am a graduate student of OR and I found Gurobi crashed my computer on a few of my IPs and I had to revert back and use CPLEX to solve.

    Did you try Gurobi support to see what the issue was? I know they are very eager to know about any problems with their system.

    As Mike said, please send details to ‘’. We have received no reports of crashes to this point. If you can tell us how to reproduce it, we’ll certainly fix it ASAP.

    For some reason this post is generating a huge number of spam comments. So I’m going to disable comments here.
