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 "smooth fictitious play in n times 2 potential games"):
  Abstract: The paper shows that smooth fictitious play converges to a neighborhood of a pure-strategy Nash equilibrium with probability 1 in almost all $N\times 2$ ($N$-player, two-action) potential games. The neighborhood of convergence may be made arbitrarily small by taking the smoothing parameter to zero. Simple proof techniques are furnished by considering regular potential games.

Includes members:
  Member "complexity theory game theory and economics":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "on communication complexity of fixed point computation")
  Member "on the exponential rate of convergence of fictitious play in potential games":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "fictitious play convergence smoothness and optimism")
