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 "the jkind model checker"):
  Abstract: JKind is an open-source industrial model checker developed by Rockwell Collins and the University of Minnesota. JKind uses multiple parallel engines to prove or falsify safety properties of infinite state models. It is portable, easy to install, performance competitive with other state-of-the-art model checkers, and has features designed to improve the results presented to users: inductive validity cores for proofs and counterexample smoothing for test-case generation. It serves as the back-end for various industrial applications.

Includes members:
  Member "efficient generation of inductive validity cores for safety properties":
    also connected through other hyperedges:
      (none)
  Member "combining k induction with continuously refined invariants":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "safety verification and refutation by k invariants and k induction extended version")
  Member "requirements analysis of a quad redundant flight control system":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "on implementing real time specification patterns using observers")
  Member "ic3 modulo theories via implicit predicate abstraction":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "complexity and information in invariant inference")
  Member "pkind a parallel k induction based model checker":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "hierarchical state machines as modular horn clauses")
