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 "near optimal multi unit auctions with ordered bidders"):
  Abstract: We construct prior-free auctions with constant-factor approximation guarantees with ordered bidders, in both unlimited and limited supply settings. We compare the expected revenue of our auctions on a bid vector to the monotone price benchmark, the maximum revenue that can be obtained from a bid vector using supply-respecting prices that are nonincreasing in the bidder ordering and bounded above by the second-highest bid. As a consequence, our auctions are simultaneously near-optimal in a wide range of Bayesian multi-unit environments.

Includes members:
  Member "on random sampling auctions for digital goods":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "double auctions in markets for multiple kinds of goods")
  Member "optimal mechansim design and money burning":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "benchmark design and prior independent optimization")
