sccmap \- extract strongly connected components of directed graphs
12
decomposes digraphs into strongly connected components
13
and an auxiliary map of the relationship between components.
14
In this map, each component is collapsed into a node.
15
The resulting graphs are printed to standard out.
16
The number of nodes, edges and strongly connected components
17
are printed to standard error.
19
is a way of partitioning large graphs into more managable pieces.
21
The following options are supported:
24
Preserve degenerate components of only one node.
27
Do not print the resulting graphs. Only the statistics are
31
Generate additional statistics. In particular,
33
prints the number of nodes, edges, connected components,
34
and strongly connected components, followed by the fraction of
35
nodes in a non-trivial strongly connected components,
36
the maximum degree of the graph, and fraction of non-tree edges
39
The following operand is supported:
42
Names of files containing 1 or more graphs in dot format.
46
the standard input will be used.
48
\fBsccmap\fP emits a warning if it encounters an undirected graph,
