Can someone please check if gurobi solves the following model in a reasonable time?

Is there an online service, where I can perform such tests?

  Hi Zohar,

  It solves in about 60s on my MacBook.

  You can always use the NEOS Server to test.

  https://neos-server.org/neos/solvers/go:Gurobi/MPS.html

  But you do need to run models (no matter which solver) with different seed values to be able to benchmark properly (see How can I make accurate comparisons?).

  Thanks for checking.

  The neos-server has a limit of 16mb on the file size.

  No problem! You may be able to work with mps.bz2 or mps.zip files too. Gurobi can read these directly and there can be a huge difference in size once compressed. I assume we're not the only solver that does this but it also depends on whether NEOS supports it.

  I thought about it, and zip compresses a 40mb to 2mb. Still, NEOS complains that the file is too large since it's probably extracts it.
