It converts between inequality and generator representations, computes adjacency and faces, and includes linear-programming support. ### Projektgeschichte The upstream README describes cddlib as a C implementation of the double description method of Motzkin et al. for generating all vertices and extreme rays of a convex polyhedron from linear inequalities, and for the reverse convex-hull computation. The ETH-hosted manual by Komei Fukuda provides the project documentation lineage and remains the detailed reference for the library and command-line programs. The current GitHub repository was created in 2018 and is now the official source repository. Its releases show the modern packaged series: 0.94j in 2018, 0.94k and 0.94l in 2020, 0.94m in 2020, and 0.94n in 2025. ### Adoptionsgeschichte cddlib is packaged broadly because computational geometry and polyhedral libraries often need a shared backend. The Homebrew input records packages across Alpine, Homebrew, Debian/Ubuntu, Fedora, MacPorts, Nix, Arch, and openSUSE-family packaging. ### Wie es verwendet wird Users link against cddlib or cddgmp from C programs, use the GMP rational build for exact arithmetic, and run tools such as cddexec, lcdd, scdd, fourier, adjacency, allfaces, projection, and redcheck for polyhedral computations. ### Warum Paket-Nerds sich dafür interessieren cddlib matters in packaging because it is a small but important scientific dependency: a C library with optional GMP exact arithmetic, command-line utilities, and a long-lived mathematical niche. Its presence in many distributions reflects the way specialized academic algorithms become infrastructure for larger mathematics systems. ### Zeitleiste - 2018: Current official GitHub repository created and release 0.94j published. - 2020: Releases 0.94k, 0.94l, and 0.94m published. - 2021: ETH-hosted cddlib manual version referenced by current curation. - 2025: Release 0.94n published. ### Related projects - The README points to GMP for rational arithmetic and describes cddlib's relationship to convex-hull computation, linear programming, and double-description polyhedral algorithms. ### Quellen -
