I’m relatively new to graphviz, and I’m coming at gvpr through the lens of a sysadmin, not a mathematician
I’m having trouble getting multiple traversals, triggered by setting $tvroot or $tvnext, to visit any node multiple times.
Before I spent much more time digging, or writing up and posting my problem here, can I check: the tvroot/tvnext description in its docs says to me that another traversal will be started if these values are set or changed.
Does “another traversal” imply that already-visited nodes should be visited again, in the follow up traversal? Or is it implicitly the case that additional traversals (starting at different roots) are only useful if the gvpr user is trying to nudge the DFS/BFS algorithms to show them that they’ve managed to miss certain nodes, and that starting at this root is a way to reach them, this time?
In other words, if the conditions in the docs for setting tvroot/tvnext and starting additional traversals hold, should I expect any node to be visited and matched by a
N predicate multiple times?
Many thanks folks!
