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 "reinforcement learning produces dominant strategies for the iterated prisoner s dilemma"):
  Abstract: We present tournament results and several powerful strategies for the Iterated Prisoner’s Dilemma created using reinforcement learning techniques (evolutionary and particle swarm algorithms). These strategies are trained to perform well against a corpus of over 170 distinct opponents, including many well-known and classic strategies. All the trained strategies win standard tournaments against the total collection of other opponents. The trained strategies and one particular human made designed strategy are the top performers in noisy tournaments also.

Includes members:
  Member "an open framework for the reproducible study of the iterated prisoner s dilemma":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "learning through probing a decentralized reinforcement learning architecture for social dilemmas")
  Member "the numpy array a structure for efficient numerical computation":
    also connected through other hyperedges:
