## Prolog graph-handling routines

lang/prolog/code/math/graph/

This package contains two programs: one for decomposing a non-weighted
directed graph into strongly connected components; and the other for
finding simple and elementary cycles in a strongly connected component.
Origin:
src.doc.ic.ac.uk:packages/prolog-pd-software/ (146.169.2.1)
as graph.tar.Z

Version: 12-JAN-91
Ports: Runs in SICStus Prolog, which is Quintus compatible and
hence uses the `standard' Edinburgh syntax. Some of the
I/O is non-portable.

The programs are commented, but a basic knowledge of graph theory
would be useful. The following are the most important references for
the algorithms behind the programs.
