Academic Programs by Solver Partners

The vendors for CPLEX, GUROBI, MOSEK and XPRESS all have academic programs that may be able to provide you with a free license for their respective solver libraries. There are two ways in which you can use these free solver licenses within GAMS:

  1. Members of these programs can either purchase a GAMS link license, which offers the same functionality as a GAMS/Solver license.
  2. Or they can extend their base system with an OSI Solver link license, which is free of charge, but does not offer the full functionality of a GAMS/Solver link license. For details please see below.

With the exception of the XPRESS and GUROBI solvers, all solver links will be activated through the GAMS licensing mechanism. If you want to use a GAMS/XPRESS-Link license you must also install the XPRESS license manager. How to set up a GAMS/GUROBI-Link license is explained here. A GAMS/Solver license has to be used within the scope of the GAMS license agreement. If you order a GAMS Solver link or an OSI Solver link, we assume that you are a member of the particular program and that the usage of the solver license will comply with the terms of the vendors license agreement as explained on their web site.
