comment Expected size of intersection in a scale-free directed graph
The algorithm resulting from the independence assumption performs acceptably. A few more details can be found in this presentation: github.com/jacquerie/IR/blob/master/slide.pdf?raw=true

comment Expected size of intersection in a scale-free directed graph
I tried both approaches, and they perform poorly against the common benchmarking datasets.

comment Combination or permutation? Some special case I can't find examples of. (Basic) [RESOLVED]
If you wish to count the number of results printed, you can use the stars and bars argument, in particular Theorem 1: en.wikipedia.org/wiki/Stars_and_bars_(combinatorics)

comment Does addition have to be defined in metric spaces?
The point I was trying to make is that a generic set has no intrinsic or natural addition, yet it is a metric space with the proper metric.

comment internal nodes in a complete binary tree
Almost. That's true when we are adding a leaf to a node that already has one: total number of nodes goes up by 1 while number of internal nodes stays the same. Then there's the case of adding a leaf to a node without children, which now becomes an internal node.

@HenningMakholm Uh, right! Thank you for making me think about this issue in its formulation.
