    3. Model sometimes works, sometimes hangs indefinitely

    Thanks, Eli. This is a really helpful answer. For context, I have fairly limited optimization experience--I'm running a model I've inherited from someone else. Whoever takes over my job in a few mo...

    3. Model sometimes works, sometimes hangs indefinitely

    For what it's worth, the log file of the forever-hanging run looks similar (to my eye) to the log file of a run that completed in 10 minutes: Gurobi 9.0.1 (mac64) logging started Tue Nov 17 22:08:5...

    Hi all, I have been using Gurobi (both in the cloud and, when that seems to fail, on my local machine) to perform optimizations for months. For the last three weeks, I have been running a high volu...

    3. High python CPU usage associated w/ Gurobi Cloud?

    Thanks, Greg. On point #1, I don't see anything like that, and I'm not quite sure where I would expect to. This may be because my call to gurobi is not directly in the script I'm running (it's call...

    Hi Greg--I'm pursuing this strategy based on the response to my previous post here. Basically, it's seemed that if I want to run many iterations of a script (each with different parameters) in para...
