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 "a logic algebraic tool for reasoning with knowledge based systems"):
  Abstract: A detailed exposition of foundations of a logic-algebraic model for reasoning with knowledge bases specified by propositional (Boolean) logic is presented. The model is conceived from the logical translation of usual derivatives on polynomials (on residue rings) which is used to design a new inference rule of algebro-geometric inspiration. Soundness and (refutational) completeness of the rule are proved. Some applications of the tools introduced in the paper are shown.

Includes members:
  Member "variable forgetting in reasoning about knowledge":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "on sufficient and necessary conditions in bounded ctl")
  Member "on the practical use of variable elimination in constraint optimization problems still life as a case study":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "when you must forget beyond strong persistence when forgetting in answer set programming")
  Member "propositional independence formula variable independence and forgetting":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "on the reasons behind decisions")
