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 "convergence time of quantized metropolis consensus over time varying networks"):
  Abstract: We consider the quantized consensus problem on undirected time-varying connected graphs with n nodes, and devise a protocol with fast convergence time to the set of consensus points. Specifically, we show that when the edges of each network in a sequence of connected time-varying networks are activated based on Poisson processes with Metropolis rates, the expected convergence time to the set of consensus points is at most O(n^2 log^2 n), where each node performs a constant number of updates per unit time.

Includes members:
  Member "convergence time for unbiased quantized consensus over static and dynamic networks":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "robotic surveillance based on the meeting time of random walks")
  Member "an upper bound on the convergence time for distributed binary consensus":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "global majority consensus by local majority polling on graphs of a given degree sequence")
  Member "convergence time analysis of quantized gossip consensus on digraphs":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "resilient randomized quantized consensus")
