colour the vertices of graphs in all distinct ways
Synopsis
vcolg [-q] [-u|-T] [-e#|-e#:#] [-m#] [-f#] [infile [outfile]]
Description
Read graphs or digraphs 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
