How to link a solver to AIMMS

If you have a license for a solver and your AIMMS license has the link to that solver (a so-called ‘link-only’ license), you can add that solver to your AIMMS.

Currently, AIMMS provides links to the following solvers:

• CPLEX

• GUROBI

• PATH

• SNOPT

• MINOS

General procedure

Before linking a solver to AIMMS, ensure a solver license is valid and installed correctly. You should be able (and allowed) to run the solver stand-alone.

Start AIMMS. Go to Settings > Solver Configuration and add the solver.

Test if the solver is added correctly.

Linking CPLEX to AIMMS

1. Make sure your CPLEX license is installed correctly, and you can run CPLEX stand-alone.

2. Go to Settings > Solver Configuration and add the CPLEX solver libcpx*.dll.

Linking GUROBI to AIMMS

1. Make sure your GUROBI license is installed correctly, and you can run GUROBI stand-alone.

2. Set the environment variable GRB_LICENSE_FILE to point to the exact location of the license file.

(For example, if the license file gurobi.lic is in the directory C:\Gurobi, then set GRB_LICENSE_FILE to C:\Gurobi\gurobi.lic.)

3. Go to Settings > Solver Configuration and add the GUROBI solver libgrb*.dll.

Linking PATH to AIMMS

1. Make sure your PATH license is installed correctly, and you can run PATH stand-alone.

2. Copy the file path*.dll to the subdirectory Solvers in AIMMS.

3. Go to Settings > Solver Configuration and add the PATH solver libpath*.dll.

Linking SNOPT or MINOS to AIMMS

Go to Settings > Solver Configuration and add the solver libsnopt*.dll or libminos.dll.

(You don’t have to copy a solver DLL file to the installation directory of AIMMS because the AIMMS installation already includes these files.)
