Acknowledgements of Support

They support research in polyhedral geometry and optimization by helping to build bridges between a variety of specialized mathematical computer softwares.

Previous Workshops

Oberwolfach RiP (April-May 2019)

  • More interface of normaliz and polymake in sage
  • release of fast qnormaliz/e-antic computations inside sage
  • Improvement of the internals
