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 "committees providing ejr can be computed efficiently"):
  Abstract: We identify a whole family of approval-based multi-winner voting rules that satisfy PJR. Moreover, we identify a subfamily of voting rules within this family that satisfy EJR. All these voting rules can be computed in polynomial time as long as the subalgorithms that characterize each rule within the family are polynomial. One of the voting rules that satisfy EJR can be computed in $O(n m k^2)$.

Includes members:
  Member "multiwinner approval rules as apportionment methods":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "evaluating approval based multiwinner voting in terms of robustness to noise")
  Member "the maximin support method an extension of the d hondt method to approval based multiwinner elections":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "a quantitative analysis of multi winner rules")
  Member "computational aspects of multi winner approval voting":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "evaluating approval based multiwinner voting in terms of robustness to noise")
