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.)
