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: "dynamic dependency pairs for algebraic functional systems"
  Abstract: We extend the higher-order termination method of dynamic dependency pairs to Algebraic Functional Systems (AFSs). In this setting, simply typed lambda-terms with algebraic reduction and separate -steps are considered. For left-linear AFSs, the method is shown to be complete. For so-called local AFSs we dene a variation of usable rules and an extension of argument lterings. All these techniques have been implemented in the higher-order termination tool WANDA.
