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 "subset synchronization of transitive automata"):
  Abstract: We consider the following generalized notion of synchronization: A word is called a resetword of a subset of states of a deterministic ﬁnite automaton if it maps all states of the setto a unique state. It is known that the minimal length of such words is superpolynomial inworst cases, namely in a series of substantially nontransitive automata. We present a series oftransitive binary automata with a strongly exponential minimal length. This also constitutesa progress in the research of composition sequences initiated by Arto Salomaa, becausereset words of subsets are just a special case of composition sequences. Deciding about theexistence of a reset word for given automaton and subset is known to be a PSPACE-completeproblem, we prove that this holds even if we restrict it to transitive binary automata.
