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: "fast kotter nielsen hoholdt interpolation in the guruswami sudan algorithm"
  Abstract: The Kotter-Nielsen-Hoholdt algorithm is a popular way to construct the bivariate interpolation polynomial in the Guruswami-Sudan decoding algorithm for Reed-Solomon codes. In this paper, we show how one can use Divide & Conquer techniques to provide an asymptotic speed-up of the algorithm, rendering its com- plexity quasi-linear in n. Several of our observations can also provide a practical speed-up to the classical version of the algorithm.

Connected through hyperedge HE-1 (induced by source paper "computing minimal interpolation bases"):
  with members:
    - "faster algorithms for multivariate interpolation with multiplicities and simultaneous polynomial approximations"
    - "powers of tensors and fast matrix multiplication"
    - "an interpolation procedure for list decoding reed solomon codes based on generalized key equations"
    - "explicit codes achieving list decoding capacity error correction with optimal redundancy"
