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 "distributed clustering for multiuser networks through coalition formation"):
  Abstract: Clustering mechanisms are essential in certain multiuser networks for achieving efficient resource utilization. This lecture note presents the theory of coalition formation as a useful tool for distributed clustering problems. We reveal the generality of the theory, and study complexity aspects which must be considered in multiuser networks.

Includes members:
  Member "distributed long term base station clustering in cellular networks using coalition formation":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "globally optimal base station clustering in interference alignment based multicell networks")
  Member "coalitional games in miso interference channels epsilon core and coalition structure stable set":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "adaptive pilot clustering in heterogeneous massive mimo networks")
  Member "coalitional games in partition form for joint spectrum sensing and access in cognitive radio networks":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "shipper cooperation in stochastic drone delivery a dynamic bayesian game approach")
