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 "representing all stable matchings by walking a maximal chain"):
  Abstract: The seminal book of Gusfield and Irving [GI89] provides a compact and algorithmically useful way to represent the collection of stable matches corresponding to a given set of preferences. In this paper, we reinterpret the main results of [GI89], giving a new proof of the characterization which is able to bypass a lot of the "theory building" of the original works. We also provide a streamlined and efficient way to compute this representation. Our proofs and algorithms emphasize the connection to well-known properties of the deferred acceptance algorithm.

Includes members:
  Member "a simply exponential upper bound on the maximum number of stable matchings":
    also connected through other hyperedges:
      (none)
  Member "stable matching mechanisms are not obviously strategy proof":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a stable marriage requires communication")
  Member "a stable marriage requires communication":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "the complexity of interactively learning a stable matching by trial and error")
  Member "manipulation of stable matchings using minimal blacklists":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "coalition manipulations of the gale shapley algorithm")
