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: "shift registers fool finite automata"
  Abstract: Let $x$ be an $m$-sequence, a maximal length sequence produced by a linear feedback shift register. We show that the nondeterministic automatic complexity $A_N(x)$ is close to maximal: $n/2-A_N(x)=O(\log^2n)$, whereas Hyde has shown $A_N(y)\le n/2+1$ for all sequences $y$.

Connected through hyperedge HE-1 (induced by source paper "superposition as memory unlocking quantum automatic complexity"):
  with members:
    - "automatic kolmogorov complexity and normality revisited"
    - "few paths fewer words model selection with automatic structure functions"
    - "nondeterministic automatic complexity of overlap free and almost square free words"

Connected through hyperedge HE-2 (induced by source paper "few paths fewer words model selection with automatic structure functions"):

    - "kolmogorov s structure functions and model selection"
