Talk:Postorder

I disagree that postorder needs to apply to control flow graphs; it can be used on any connected graph. For example, I was using it just now on a call graph with cycles. I think it could be made another definition in glossary of graph theory, with a redirect from this topic (like subgraph, for example). The explanation of how to derive strongly connected components from two depth first searches would then make more sense too (replace "order of finishing times" with "postorder number", however you say that properly). --Mike Van Emmerik 06:33, 24 January 2006 (UTC)
