Query: Network Growth with Preferential Attachment for High Indegree and Low
  Outdegree   We study the growth of a directed transportation network, such as a food web,
in which links carry resources. We propose a growth process in which new nodes
(or species) preferentially attach to existing nodes with high indegree (in
food-web language, number of prey) and low outdegree (or number of predators).
This scheme, which we call inverse preferential attachment, is intended to
maximize the amount of resources available to each new node. We show that the
outdegree (predator) distribution decays at least exponentially fast for large
outdegree and is continuously tunable between an exponential distribution and a
delta function. The indegree (prey) distribution is poissonian in the
large-network limit.
