human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "a partisan districting protocol with provably nonpartisan outcomes"
  Abstract: We design and analyze a protocol for dividing a state into districts, where parties take turns proposing a division, and freezing a district from the other party's proposed division. We show that our protocol has predictable and provable guarantees for both the number of districts in which each party has a majority of supporters, and the extent to which either party has the power to pack a specific population into a single district.

Connected through hyperedge HE-1 (induced by source paper "selecting voting locations for fun and profit"):
  with members:
    - "network based vertex dissolution"
    - "on voting and facility location"
    - "more natural models of electoral control by partition"
    - "combinatorial voter control in elections"
    - "weighted electoral control"
    - "how hard is bribery in elections"
    - "anyone but him the complexity of precluding an alternative"

Connected through hyperedge HE-2 (induced by source paper "on partisan bias in redistricting computational complexity meets the science of gerrymandering"):
  with members:
    - "alleviating partisan gerrymandering can math and computers help to eliminate wasted votes"
