I see what you mean by having a biased logic that would prefer shorter
paths to longer ones, I had not thought about that.
Regarding the self-reference part, I think it would not be a problem
because of the structure of my particular (directed) graph. In fact, each
node represents an assignment *at some given time period* and the outward
neighbors of a node represent assignments *in the future*. In this way, a
path can never visit a previously visited node since there are no possible
cycles. In fact I can easily calculate the shortest and longest possible
path between two nodes (shortest: using graphql's `shortest_distance`
method, longest= number of periods in between the two nodes).
So the paths I want to create (or sample) are just the different ways one
can go from a node N1 (in period P1) to node N2 (in period P2 > P1).
I think that in my graph I could just sample neighbors with a weight that
depends on how far they are (in number of periods) from the node: the
farthest neighbor will have the least probability of being chosen. This
way, I'd compensate the fact that shorter paths take less hops.

Well, for DAG (directed acyclic graphs) the situation is quite
different, you should have said so in the beginning.

What do you think?
Why do I get the impression I'm using google more than you to answer
your question?
