See the features which were new in Release 2.10.
New features include
The final alpha release. Besides more bug fixes, this version contains the following new features:
polymake can deal with finite simplicial complexes again. To this end there is a new object type
SimplicialComplex. Look at the introductory tutorial.
Constructions like deletion, contraction or dual can now be computed.
New classes Polynomial and Ring allow basic computations with polynomials. See our brief tutorial.
The automatic extraction of the documentation from the code is now working again and significantly improved.
Additionally the documentation of all applications released is available online.
This was supposed to be the last alpha release.
Besides a lot of bug fixes, contains the following new features:
The application has now basic functionality like computations between CIRCUITS, COCIRCUITS, and BASES of a matroid and constructing graphical matroids.
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.
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.
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).
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.
