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 "from social simulation to integrative system design"):
  Abstract: The purpose of this White Paper of the EU Support Action “Visioneer” (see www.visioneer.ethz.ch) is to address the following goals: #R##N##R##N#1.#R##N##R##N#Develop strategies to build up social simulation capacities.#R##N##R##N##R##N##R##N##R##N#2.#R##N##R##N#Suggest ways to build up an “artificial societies” community that aims at simulating real and alternative societies by means of supercomputers, grid or cloud computing.#R##N##R##N##R##N##R##N##R##N#3.#R##N##R##N#Derive proposals to establish centers for integrative systems design.

Includes members:
  Member "how to create an innovation accelerator":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "an analytical framework to nowcast well being using mobile phone data")
  Member "from social data mining to forecasting socio economic crises":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "a data mining framework to model consumer indebtedness with psychological factors")
  Member "parallel implementation of the transims micro simulation":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "distributed macroscopic traffic simulation with open traffic models")
