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: "extended aiger format for synthesis"
  Abstract: We extend the AIGER format, as used in HWMCC, to a format that is suitable to define synthesis problems with safety specifications. We recap the original format and define one format for posing synthesis problems and one for solutions of synthesis problems in this setting.
