human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "exploiting independent subformulas a faster approximation scheme for k sat"):
  Abstract: We present an improvement on Thurley@?s recent randomized approximation scheme for #k-SAT where the task is to count the number of satisfying truth assignments of a Boolean function @F given as an n-variable k-CNF. We introduce a novel way to identify independent substructures of @F and can therefore reduce the size of the search space considerably. Our randomized algorithm works for any k. For #3-SAT, it runs in time O(@e^-^2@?1.51426^n), for #4-SAT, it runs in time O(@e^-^2@?1.60816^n), with error bound @e.
