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 the complexity of nash equilibria in anonymous games"):
  Abstract: We show that the problem of finding an {\epsilon}-approximate Nash equilibrium in an anonymous game with seven pure strategies is complete in PPAD, when the approximation parameter {\epsilon} is exponentially small in the number of players.

Includes members:
  Member "inapproximability of nash equilibrium":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "the complexity of interactively learning a stable matching by trial and error")
