Sage Days 84 : Polytopes (in Sage, Python, polymake and more)

February 27th - March 10th 2017 Olot, Catalunya, Spain

These (Sage) days will be focused on Polytopes and linear programming. This workshop is dedicated to people already familiar with Sage or being active in some polytope related libraries/software.

There is a very limited number of places. If you are interested get quickly in contact with Vincent Delecroix (vincentDOTdelecroixATuDASHbordeaux.fr).

During the workshop participants will have to cook several times for everybody. Bring your favorite recipies!

Practical information

The Sage Days will happen at FABER in Olot. It is a small town close to Girona (55km) and Barcelona (110km). You can find very detailed practical information about how to reach Faber HERE.
