SYNOPSIS
vcolg
[,-q/] [,-u|-T|-G|-A|-B/] [,-e#|-e#:#/] [,-m#/] [,-f#/] [,-D#|-r#|-l#/] [,infile /[,outfile/]]
DESCRIPTION
-
Read undirected loop-free graphs and colour their vertices in
-
in all possible ways with colours 0,1,2,... .
Isomorphic graphs derived from the same input are suppressed.
If the input graphs are non-isomorphic then the output graphs are also.
- -e# | -e#:#
-
specify a value or range of the total value of the colours
-
-m# number of available colours (default 2)
-
-f# Use the group that fixes the first # vertices setwise
- -T
-
- use a simple text output format (nv ne {col} {v1 v2})
- -u
-
no output, just count them
- -q
-
suppress auxiliary information
