Overview
-
Extract random graph/digraphs 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,
-
but is always digraph6 if
-zis used.
-
-z -
Treat the input as a directed graph
-
-o -
Treat the input as a directed graph and output an oriented graph
-P# or-P#/#-
Specify a probability p.
-P# is the same as-P1/#
-
-m# -
Make this many outputs for each input (default 1)
-
-l -
Canonically label outputs.
-
-S# -
Set seed for random numbers (default nondeterministic)
-
Usually each edge is kept with probability p. In the case of
-o, each edge in one direction only is kept
-
with probability p. For edges in both directions, with probability p keep one direction randomly chosen and with probability 1-p delete both directions. Thus
-oP1will make a random orientation of an undirected graph.
-
-q -
Suppress auxiliary information.
