human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "extending the d wave with support for higher precision coefficients"
  Abstract: D-Wave only guarantees to support coefficients with 4 to 5 bits of resolution or precision. This paper describes a method to extend the functionality of the D-Wave to solve problems that require the support of higher precision coefficients.

Connected through hyperedge HE-1 (induced by source paper "quantum annealing based binary compressive sensing with matrix uncertainty"):
  with members:
    - "bilinear adaptive generalized vector approximate message passing"
    - "nonnegative binary matrix factorization with a d wave quantum annealer"
    - "sharp rip bound for sparse signal and low rank matrix recovery"
    - "sparsity cognizant total least squares for perturbed compressive sampling"
    - "general deviants an analysis of perturbations in compressed sensing"

Connected through hyperedge HE-2 (induced by source paper "on post processing the results of quantum optimizers"):
  with members:
    - "nonnegative binary matrix factorization with a d wave quantum annealer"
    - "effective optimization using sample persistence a case study on quantum annealers and various monte carlo optimization methods"
    - "stochastic characteristics of qubits and qubit chains on the d wave 2x"
