(description
|
||||
"The C code of lrslib implements the reverse search algorithm for
|
||||
vertex enumeration and convex hull problems. Its input file format is
|
||||
compatible with cddlib. All computations are done exactly in either
|
||||
multiple precision or fixed integer arithmetic. Output is not stored
|
||||
in memory, so even problems with very large output sizes can sometimes
|
||||
be solved.")
