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 "clustering encoding and diameter computation algorithms for multidimensional data"):
  Abstract: In this paper we present novel algorithms for several multidimensional data processing problems. We consider problems related to the computation of restricted clusters and of the diameter of a set of points using a new distance function. We also consider two string (1D data) processing problems, regarding an optimal encoding method and the computation of the number of occurrences of a substring within a string generated by a grammar. The algorithms have been thoroughly analyzed from a theoretical point of view and some of them have also been evaluated experimentally.

Includes members:
  Member "multidimensional data structures and techniques for efficient decision making":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "efficient algorithms for several constrained activity scheduling problems in the time and space domains")
  Member "optimal geometric partitions covers and k centers":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "optimal constrained resource allocation strategies under low risk circumstances")
