See the features which were new in Release 2.10.

Release 2.9.9 - November 9, 2010

New features include

  • upon multiple requests: completely rewritten configuration
  • distribution comes with JReality for interactive visualization
  • improved extension management, including versioning and oblivion
  • Perl 5.12 support
  • partial support of Cygwin: basic operatons work, crashes may occur due to incomplete exception handling

Release 2.9.8 - March 17, 2010

The final alpha release. Besides more bug fixes, this version contains the following new features:

application "topaz"

Finally polymake can deal with finite simplicial complexes again. To this end there is a new object type SimplicialComplex. Look at the introductory tutorial.

application "polytope"

  • New visualisation method for polytopal subdivisions.
  • Project-and-lift approach to enumerate lattice points
  • improved methods for conversion to ambient/vertex lattice

application "matroid"

Constructions like deletion, contraction or dual can now be computed.

Polynomials and Rings

New classes Polynomial and Ring allow basic computations with polynomials. See our brief tutorial.

documentation and interactive help

The automatic extraction of the documentation from the code is now working again and significantly improved.

  • new installation level command 'make docs' to build local copy of documentation including local extensions
  • vastly improved TAB completion
  • new feature: F1 key for context sensitive help

Additionally the documentation of all applications released is available online.

Release 2.9.7 - September 22, 2009

This was supposed to be the last alpha release.

Besides a lot of bug fixes, contains the following new features:

application "matroid"

The application has now basic functionality like computations between CIRCUITS, COCIRCUITS, and BASES of a matroid and constructing graphical matroids.

object PointConfiguration

The application “polytope” has a new object PointConfiguration that allows to deal also with non-convex point configurations. In particular, one can now deal with triangulations of point configurations without having to rely on TRIANGULATION_INT, and a visualization of point configurations and their triangulations is possible.

Lattice Polytopes

Most methods in polymake dealing with lattice polytopes assume that the polytope is full-dimensional in the integer lattice. Two new methods transform a given lattice polytope into a full-dimensional lattice polytope either using the induced integer lattice or the lattice spanned by the vertices.

There are several new constructions that return lattice polytopes: pyramids, bipyramids, transportation polytopes, and cayley polytopes.

Lattice isomorphism for smooth polytopes can be checked.

Compatibility

polymake can be compiled and used with recently published versions gcc 4.3, gcc 4.4, perl 5.10.1, and under MacOS 10.6 (Snow Leopard).

Release 2.9.6 - February 23, 2009

The next alpha release.

Primarily contains bug fixes.

The issue concerning possible data inconsistency has been solved. A new family of permutation subobjects and related rules has been introduced. They are in charge of synchronizing production rules whose outputs may differ from each other by a permutation of some elements (mainly these are the vertices or facets of a polytope).

Other shortcomings from the list below still persist.

If you are going to compile polymake from the source code, please be careful with the choice of the right gcc version. Currently there are too many gcc versions and snapshots out there, each being broken in its individual way. Still worse, no one popular Linux distribution offers a stable official gcc release as its standard compiler. Instead, they all use some accidental snapshots mixed with proprietary patches. This makes it impossible to give any reliable recommendations now. From our limited experience we can confirm that the official gcc 4.3.3 is OK, as well as the snapshot being shipped with opensuse 11.1 . The Apple's XCode does well too. In all other cases: Please, try your luck and give us a feed back on our faq page.
