NAME
nauty-delptg - delete vertices
SYNOPSIS
delptg
[,-lq/] [,-a|-b/] [,-d#|-d#:#/] [,-v#|-v#:#/] [,-r#/] [,-n#/] [,-m#|-i/] [,infile /[,outfile/]]
DESCRIPTION
-
Delete some vertices from a file of graphs.
-
The output file has a header if and only if the input file does.
No isomorph reduction is done.
- -l
-
Canonically label outputs
-
-d# -d#:# Only remove vertices with original degree in the given range
-
- For digraphs, the out-degree is used.
-
-n# The number of vertices to delete (default 1).
-
-v# -v#:# Vertex number or numbers that it is allowed to delete
-
(first vertex is number 0).
-
-m# Lower bound on minimum degree of output graphs.
-
-r# Choose # random sets of points (not necessarily different)
- -a
-
- The deleted points must be adjacent.
- -b
-
The deleted points must be non-adjacent.
- -i
-
Leave deleted vertices as isolates, not compatible with -m.
-
No empty graphs are output. No warning is issued if
-
-d, -v -n, -m together imply no graphs are output.
-
For digraphs, out-degree is used for -d and -m.
-q Suppress auxiliary information
