Due to our collaboration with our solver partners for CPLEX, GUROBI , MOSEK, XPRESS, there have been a few changes regarding the licensing of these solvers. The solver vendors now offer a free academic license to members of their academic initiative programs.

With the exception of the XPRESS solver, all solver links will be activated through the GAMS licensing mechanism. A GAMS/Solver license has to be used within the scope of the GAMS license agreement.
