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 "braid is undecidable"):
  Abstract: Braid is a 2008 puzzle game centered around the ability to reverse time. We show that Braid can simulate an arbitrary computation. Our construction makes no use of Braid's unique time mechanics, and therefore may apply to many other video games. #R##N#We also show that a plausible "bounded" variant of Braid lies within 2-EXPSPACE. Our proof relies on a technical lemma about Turing machines which may be of independent interest. Namely, define a braidlike Turing machine to be a Turing machine that, when it writes to the tape, deletes all data on the tape to the right of the head. We prove that deciding the behavior of such a machine lies in EXPSPACE.
