undirected graph

[DanqingZ]

If I have an undirected graph, but I did not put -s in the command line, will the result be affected? Based on my result and ligra.h file, I think no, but just want to double check. Many thanks!

The result won't be affected. Without the -s flag there will be a preprocessing step that generates the incoming edges for each vertex.

Thanks!
