Unit 1. 2 : Discover GAMS

Welcome to the second unit of the introduction sequence to mathematical programming. We suggest you watch a video of the theoretical contents and download the slideshow of the lesson thanks to the corresponding links. You may then do one or several activities for each lesson. The model construction activities may use models already developed in a previous unit. If you have not done the activity in question, you may find the relevant model in the Model library.

In this unit, you will find “Additional activities” to do in order to reinforce your skills.
