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 "a counter example to karlin s strong conjecture for fictitious play"):
  Abstract: Fictitious play is a natural dynamic for equilibrium play in zero-sum games, proposed by Brown [6], and shown to converge by Robinson [33]. Samuel Karlin conjectured in 1959 that fictitious play converges at rate O(t -- 1/2) with respect to the number of steps t. We disprove this conjecture by showing that, when the payoff matrix of the row player is the n × n identity matrix, fictitious play may converge (for some tie-breaking) at rate as slow as a#x3A9;(t -- 1/n).

Includes members:
  Member "optimization learning and games with predictable sequences":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "provably efficient adaptive approximate policy iteration")
  Member "on the approximation performance of fictitious play in finite games":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "learning convex partitions and computing game theoretic equilibria from best response queries")
