v3.9.0
def11a1

Normaliz now uses the e-antic release 1.0.1 for algebraic polyhedra:

https://github.com/flatsurf/e-antic/releases/tag/1.0.1

This requires the update of other optional packages, which is handled automatically by the included install scripts.. (See INSTALL or thedetails.)

Algorithmic extensions (in addition to various small improvements):

  1. We have added the Lawrence algorithm for polytope volumes by signed decomposition into simplices. It opens a new order of magnitude for volume computations for polytopes defined by few inequalities.
  2. The descent algorithm for volumes now has a variant exploiting isomorphisms of faces.
  3. One can compute "raw" automorphism groups directly from the input data.
  4. One can now ask for pulling triangulations and placing triangulations.

The corresponding version of PyNormaliz is 2.15:

https://github.com/Normaliz/PyNormaliz/releases/tag/v2.15

IMPORTANT. normaliz-3.9.0.zip and tar.gz uploaded July 2 were incomplete. The critical file missing was install_scripts_opt/install_nmz_antic.sh. You can extract it from the source repositories automatically created by GitHub or (better) extract the new version attached now.

February 08, 2022: Use Mac binary only with -x=1 or update to version 3.9.2.
