Skeleton: Implementation of Double Description Method
Skeleton is a new fast implementation of
Double Description Method (DDM) [1] for generating all extreme rays of a polyhedral cone.
Now sources are available. Float, integer and arbitrary precision integer
arithmetics is supported.
The implementation uses Arageli
library for exact computation.
