human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "coco the bi objective black box optimization benchmarking bbob biobj test suite"):
  Abstract: The bbob-biobj test suite contains 55 bi-objective functions in continuous domain which are derived from combining functions of the well-known single-objective noiseless bbob test suite. Besides giving the actual function definitions and presenting their (known) properties, this documentation also aims at giving the rationale behind our approach in terms of function groups, instances, and potential objective space normalization.

Includes members:
  Member "biobjective performance assessment with the coco platform":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "using well understood single objective functions in multiobjective black box optimization test suites")
  Member "coco the experimental procedure":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "using well understood single objective functions in multiobjective black box optimization test suites")
  Member "coco a platform for comparing continuous optimizers in a black box setting":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "using a thousand optimization tasks to learn hyperparameter search strategies")
