Sage Days 84 : Polytopes (in Sage, Python 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!
Coming to Olot
The Sage Days will happen at FABER in Olot. It is a small town close to Girona (55km) and Barcelona (110km). To reach Olot there are at least two options:
buses TEISA from either Girona or Barcelona
Projects
 develop interfaces to polytope libraries/softwares (ppl, polymake, etc)
moving as independent Python packages the Sage interfaces to cdd, ppl, etc (see e.g. pplpy)
 make a generic number field implementation in C/C++ using normaliz
 add mutable polytopes in Sage
Delaunay/Voronoi polytopes of lattices (> algorithm for norm form equation)
#22006: CBC tries to use system's blas at runtime which creates an error
#20302: Metaticket: Improvements to MixedIntegerLinearProgram etc.
