Introduction to GAMS and GAMSIDE

Open Access Training

This page provides open access to training materials that provide an introduction to GAMS and GAMSIDE. The materials are adapted from the standard GAMS tutorial to provide training that complements the GAMS tutorial. The materials require the use of a USER LIBRARY; so studying the instructions on the operation of a User Library is necessary.

We will add training materials for GAMS Studio when difficulties with using Studio with User Libraries have been resolved (or an alternative method of delivery has been determined).

ALL these exercises only require the demo version of GAMS. To apply for a demo license from GAMS corporation and download the latest version of GAMS, click here to go the the GAMS website.

This material is UNSUPPORTED.
