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.

Projects
You can have a look at our list of Sage tickets with days84 tags
 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.
release the real embedded number fields library (built on top of antic)
#21950: Add pulling_triangulation method to polyhedron class and point configuration
 Uniform random generation of integer points in polytopes
 Survey existent maintained Python bindings to MILP solvers, and see if we could use them instead of our own, those include pyomo, pulp, numberjack,...
Atomic and Coatomic lattice Refactor this function so that it returns a lattice and so that you can input only one of the two incidences.
#22420:Metaticket: Polytopes, polyhedron and their properties Increase the functionalities of polyhedron class
