C library implementing the Double Description Method

Official package sites : https://www.inf.ethz.ch/personal/fukudak/cdd_home/ ·

The C-library cddlib is a C implementation of the Double Description Method of Motzkin et al. for generating all vertices (i.e. extreme points) and extreme rays of a general convex polyhedron in R^d given by a system of linear inequalities: P = { x=(x1, ..., xd)^T : b - A x >= 0 } where A is a given m x d real matrix, b is a given m-vector and 0 is the m-vector of all zeros. The program can be used for the reverse operation (i.e. convex hull computation). This means that one can move back and forth between an inequality representation and a generator (i.e. vertex and ray) representation of a polyhedron with cdd. Also, cdd can solve a linear programming problem, i.e. a problem of maximizing and minimizing a linear function over P.

sci-libs/cddlib: make MY_PV assignment more reliable.
François Bissey came up with a better way (using bash substrings) to compute MY_PV from PV in these ebuilds. It won't work forever, but it should be OK for a few more versions, and the failure mode is nicer than the present one of silently downloading the wrong version.

sci-libs/cddlib: new upstream version 0.94m.
This version moves the header files to a soon-to-be-standard location (so that Debian, Fedora, et cetera don't all have to move them) and is going to break some consumers as a result. For that reason, I opted not to package the previous version right away. This version, however, contains a critical bug fix as well. So users need the option to upgrade.

sci-libs/cddlib: new version 094j.
François Bissey had an ebuild for the latest version of this package in the sage-on-gentoo overlay, so I've imported it with minor changes: * Updated to EAPI=7 (no related changes). * Dropped the unused autotools.eclass inherit. * Changed GPL-2 to GPL-2+, since the files that do have copyright headers have the "or any later version" bit. * Dropped the DOCS declaration; they're all covered by einstalldocs. * Added IUSE=examples. * Reworked the documentation/example installation logic. The new autotools build system installs everything by default, so if the user doesn't want something, we have to kill it from $ED. I've also added the upstream remote to metadata.xml, and added myself and François as maintainers in the future. SageMath uses two cddlib executables only present as of this version, so it's a prerequisite for moving more of SageMath into the tree.

proj/gentoo: Initial commit
This commit represents a new era for Gentoo: Storing the gentoo-x86 tree in Git, as converted from CVS. This commit is the start of the NEW history. Any historical data is intended to be grafted onto this point. Creation process: 1. Take final CVS checkout snapshot 2. Remove ALL ChangeLog* files 3. Transform all Manifests to thin 4. Remove empty Manifests 5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$ 5.1. Do not touch files with -kb/-ko keyword flags. Signed-off-by: Robin H.
