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 "on enumerating distributions for associated vectors in the entropy space"):
  Abstract: This paper focuses on the problem of finding a distribution for an associated entropic vector in the entropy space nearest to a given, possibly non-entropic, target vector for random variables with a constraint on alphabet size. We show the feasibility to find distribution for associated vector via a sequence of perturbations in the probability mass function. Then we present an algorithm for numerically solving the problem together with extensions, applications, and comparison with the known results.

Includes members:
  Member "entropy region and convolution":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "how to use undiscovered information inequalities direct applications of the copy lemma")
  Member "group characterizable entropy functions":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "bag query containment and information theory")
