NAME¶

nauty-complg - complement graphs

SYNOPSIS¶

complg [-lq] [-a] [-L] [-r|-R] [infile [outfile]]

DESCRIPTION¶

Take the complements of a file of graphs.

The output file has a header if and only if the input file does. The output format is defined by the header or first graph.

-r

Only complement if the complement has fewer directed edges.

-R

Only complement if the complement has fewer directed edges or has the same number of directed edges and is canonically less than the original.

-a

Also output the input graph (before the complement).

-L

Complement the loops too. By default, preserve them.

-l

Canonically label outputs.

-q

Suppress auxiliary information.
