lrslib: Reverse search algorithm for vertex enumeration and convex hull problems¶
Description¶
lrslib implements the linear reverse search algorithm of Avis and Fukuda.
See the homepage (http://cgm.cs.mcgill.ca/~avis/C/lrs.html) for details.
We use an autotoolized version from https://github.com/mkoeppe/lrslib/tree/autoconfiscation
License¶
lrslib is released under a GPL v2+ license.

Dependencies¶
To build and install the “plrs” binary, a multi-thread version of lrs, need to first install the full Boost package (“sage -i boost”).
If the package finds an MPI C++ compiler script (mpic++), it also builds and installs the “mplrs” binary, a distributed version of lrs using MPI.
(Sage currently does not make use of plrs and mplrs.)
Special Update/Build Instructions¶
Type¶
optional
Equivalent System Packages¶
arch:
$ sudo pacman -S lrslib
conda:
$ conda install lrslib
opensuse:
$ sudo zypper install lrslib
See https://repology.org/project/lrslib/versions
However, these system packages will not be used for building Sage because spkg-configure.m4 has not been written for this package; see https://trac.sagemath.org/ticket/27330
