nauty-directg(1)
generate small digraphs with given underlying graph
SYNOPSIS
directg
[,-q/] [,-u|-T|-G/] [,-V/] [,-o/] [,-f#/] [,-e#|-e#:#/] [,-s#/#/] [,infile /[,outfile/]]
DESCRIPTION
-
Read undirected graphs and orient their edges in all possible ways.
-
Edges can be oriented in either or both directions (3 possibilities).
Isomorphic directed 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 number of arcs
- -o
-
orient each edge in only one direction, never both
- -f#
-
Use only the subgroup that fixes the first # vertices setwise
- -T
-
use a simple text output format (nv ne edges) instead of digraph6
- -G
-
like -T but includes group size as third item (if less than 10^10)
-
The group size does not include exchange of isolated vertices.
- -V
-
only output graphs with nontrivial groups (including exchange of
- isolated vertices).
-
The -f option is respected.
- -u
-
no output, just count them
- -s#/#
-
Make only a fraction of the orientations: The first integer is
-
the part number (first is 0) and the second is the number of
parts. Splitting is done per input graph independently.
- -q
-
suppress auxiliary information
