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 "direction reversing quasi random rumor spreading with restarts"):
  Abstract: In a recent work, Doerr and Fouz [\emph{Asymptotically Optimal Randomized Rumor Spreading}, in ArXiv] present a new quasi-random PUSH algorithm for the rumor spreading problem (also known as gossip spreading or message propagation problem). Their \emph{hybrid protocol} outperforms all known PUSH protocols. #R##N#In this work, we add to the hybrid protocol a direction-reversing element. We show that this \emph{direction-reversing quasi-random rumor spreading protocol with random restarts} yields a constant factor improvement over the hybrid model, if we allow the same dose of randomness. #R##N#Put differently, our protocol achieves the same broadcasting time as the hybrid model by employing only (roughly) half the number of random choices.

Includes members:

  Member "quasirandom rumor spreading":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "lower bounds for the happy coloring problems")
