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: "using kolmogorov complexity for understanding some limitations on steganography"
  Abstract: Recently perfectly secure steganographic systems have been described for a wide class of sources of covertexts. The speed of transmission of secret information for these stegosystems is proportional to the length of the covertext. In this work we show that there are sources of covertexts for which such stegosystems do not exist. The key observation is that if the set of possible covertexts has a maximal Kolmogorov complexity, then a high-speed perfect stegosystem has to have complexity of the same order.

Connected through hyperedge HE-1 (induced by source paper "constructing perfect steganographic systems"):
  with members:
    - "efficient generation of random bits from finite state markov chains"
    - "fast enumeration of combinatorial objects"
    - "minimum description length induction bayesianism and kolmogorov complexity"
