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!
- 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)
release the real embedded number fields library (built on top of antic)
- 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.
