Where can I get more information about AMPLs interface to specific solvers?
Many solver options can be specified directly from AMPL. You don’t need to prepare separate “spec files” or run solvers outside the AMPL environment in order to get the benefits of these options. If you are using the student edition software that comes with the AMPL book, then you will find a guide to using the packaged solvers (MINOS and CPLEX) in a booklet (“Using the AMPL Plus Student Edition Under Microsoft Windows”) that is packaged with the book. For the professional edition of AMPL, separate guides to solver directives are available online, from the solver developers, or both. See the AMPL solver listing for more information.
