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
