Unit 2.1 : Enriching the base model

Welcome to the first unit of the second sequence on mathematical programming.
From this sequence on, many lessons will be divided into several learning stages with a video of the theoretical contents, an example/exercise to try and do on your own and a self-correction video in GAMS. You may download the slides at any step. Model construction activities may use models already written in a previous unit. If you have not done the activity in question, you may find the relevant model in the “Model Library”.
