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 "proving looping and non looping non termination by finite automata"):
  Abstract: A new technique is presented to prove non-termination of term rewriting. The basic idea is to find a non-empty regular language of terms that is closed under rewriting and does not contain normal forms. It is automated by representing the language by a tree automaton with a fixed number of states, and expressing the mentioned requirements in a SAT formula. Satisfiability of this formula implies non-termination. Our approach succeeds for many examples where all earlier techniques fail, for instance for the S-rule from combinatory logic.

Includes members:
  Member "on the complexity of equivalence of specifications of infinite objects":
    also connected through other hyperedges:
      (none)
  Member "transforming outermost into context sensitive rewriting":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "entailment among probabilistic implications")
  Member "local termination theory and practice":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "sparse tiling through overlap closures for termination of string rewriting")
