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: "evomaster evolutionary multi context automated system test generation"
  Abstract: This paper presents EVOMASTER, an open-source tool that is able to automatically generate system level test cases using evolutionary algorithms. Currently, EVOMASTER targets RESTful web services running on JVM technology, and has been used to find several faults in existing open-source projects. We discuss some of the architectural decisions made for its implementation, and future work.
