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 reply to hofman on why lp cannot solve large instances of np complete problems in polynomial time"):
  Abstract: Using an approach that seems to be patterned after that of Yannakakis, Hofman argues that an NP-complete problem cannot be formulated as a polynomial bounded-sized linear programming problem. He then goes on to propose a "construct" that he claims to be a counter-example to recently published linear programming formulations of the Traveling Salesman Problem (TSP) and the Quadratic Assignment Problems (QAP), respectively. In this paper, we show that Hofman's construct is flawed, and provide further proof that his "counter-example" is invalid.

Includes members:
  Member "equality of complexity classes p and np linear programming formulation of the quadratic assignment problem":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "report on article the travelling salesman problem a linear programming formulation")
  Member "report on article p np linear programming formulation of the traveling salesman problem":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "report on article the travelling salesman problem a linear programming formulation")
