bcomps - biconnected components filter for graphs
bcomps [ -stvx?
] [ -ooutfile ] [ files ]
bcomps decomposes graphs into their
biconnected components, printing the components to standard output.
following options are supported:
- No output graph is printed. Implies the
- Print the underlying block-cutvertex tree.
- Each biconnected component
is printed as a separate root graph.
- Prints number of blocks and cutvertices.
- -o outfile
- If specified, each root graph will be written to a different
file with the names derived from outfile. In particular, if both -o and
-x flags are used, then each block is written to a different file. If outfile
does not have a suffix, the nth block of the ith graph is written to outfile_n_i.
However, the 0th block of the 0th graph is written to outfile.
has a suffix, i.e., has the form base.sfx, then the files will have the same
name as above, except appended with .sfx.
The block-cutvertex tree of ith
graph is written to outfile_n_T, with an appended suffix if specified.
default, each input graph is printed, with each block given as a subgraph
whose name is a concatenation of the name of the input graph, the string
"_bcc_" and the number of the block.
The following operand is supported:
returns 0 if all the input graphs are biconnected; and non-zero if any graph
has multiple blocks, or any error occurred.
It is possible, though unlikely,
that the names used for connected components and their subgraphs may conflict
with existing subgraph names.

operand is specified, the standard input will be used.
