16.2  How to load the library

To use the library, you must have an MP solver that eplex can use. This can be an open-source solver such as the COIN-OR project’s CLP/CBC solvers, which is distributed with ECLiPSe, or a commercial solver such as XPRESS-MP or CPLEX. Your ECLiPSe should be configured to load in a ‘default’ solver if there is more than one available.

See the library manual’s Eplex chapter for details for how to install the solver.

When configured properly, the library can be loaded with the directive:

:- lib(eplex).

This will load the library with the default external MP solver.

You probably need a valid license in order to use an external commercial solver.
