How do I use GAMS with Gurobi?

If you have a standalone Gurobi license (free academic or commercial) and want to call Gurobi from inside GAMS, you need a Gurobi/GAMS link. There are two options:

• You can add the paid Gurobi-Link license to your GAMS installation. This link license can be purchased from GAMS directly. You can find details about this on the GAMS homepage.
  • The Gurobi version used in GAMS is independent of your own installed version. See this part of the GAMS Documentation: Setting up a GAMS/Gurobi-Link license.
• You can use the free OSIGUROBI link. Please note that the free link is not guaranteed to support all of Gurobi's features.

Once GAMS is installed and licensed, you can specify Gurobi as the solver:

gams trnsport lp=gurobi
