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 "grothendieck type inequalities in combinatorial optimization"):
  Abstract: We survey connections of the Grothendieck inequality and its variants to combinatorial optimization and computational complexity.

Includes members:
  Member "the p versus np problem":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "the lagrangian remainder of taylor s series distinguishes mathcal o f x time complexities to polynomials or not")
  Member "approximating matrix p norms":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "adversarially robust low dimensional representations")
  Member "sharp kernel clustering algorithms and their associated grothendieck inequalities":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "grothendieck constant is norm of strassen matrix multiplication tensor")
  Member "approximate kernel clustering":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "how bad is worst case data if you know where it comes from")
  Member "approximate graph coloring by semidefinite programming":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "positive semidefinite programming mixed parallel and width independent")
