That sounds a bit bizarre: in my code, fromDepth(n) toDepth(n) seems to be
working like atDepth(n) if n0 (that's what should be happening, isn't it?)

One other option is to have a set of nodes, each of which represents a
component. You can create a relationships of type OWNS (or whatever) to
each of the nodes of a given component. This makes component lookup rather
simple (just grab the node that represents the component, then traverse all
of
run times of over 10 seconds (entire graph exhausted), and in most
cases it completes in between 0-4 seconds

Hiding specific relationship types is really easy, but I haven't found a

iterating over the nodes, and getting edges that way be substantially faster
despite touching each edge twice?
