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 "selecting algorithms for black box matrices checking for matrix properties that can simplify computations"):
  Abstract: Processes to automate the selection of appropriate algorithms for various matrix computations are described. In particular, processes to check for, and certify, various matrix properties of black box matrices are presented. These include sparsity patterns and structural properties that allow "superfast" algorithms to be used in place of black-box algorithms. Matrix properties that hold generically, and allow the use of matrix preconditioning to be reduced or eliminated, can also be checked for and certified - notably including in the small-field case, where this presently has the greatest impact on the efficiency of the computation.

Includes members:
  Member "linear time interactive certificates for the minimal polynomial and the determinant of a sparse matrix":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "elimination based certificates for triangular equivalence and rank profiles")
  Member "essentially optimal interactive certificates in linear algebra":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "elimination based certificates for triangular equivalence and rank profiles")
