Unit 1.3 : Primal problem, dual problem

Welcome to the third and final unit of the first sequence on mathematical programming.
For each lesson, we suggest that you watch a video of the theoretical contents and download the slides of the lesson thanks to the matching links. Each lesson is then divided into one or several activity. 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”.
At the end of this unit, you may go to the “Unit 1.4 : Application exercise” in order to put the recently acquired knowledge into practice.
