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: "mechanism design for aggregating energy consumption and quality of service in speed scaling scheduling"
  Abstract: We consider a strategic game, where players submit jobs to a machine that executes all jobs in a way that minimizes energy while respecting the given deadlines. The energy consumption is then charged to the players in some way. Each player wants to minimize the sum of that charge and of their job's deadline multiplied by a priority weight. Two charging schemes are studied, the proportional cost share which does not always admit pure Nash equilibria, and the marginal cost share, which does always admit pure Nash equilibria, at the price of overcharging by a constant factor.

Connected through hyperedge HE-1 (induced by source paper "scheduling under dynamic speed scaling for minimizing weighted completion time and energy consumption"):
  with members:
    - "resource cost aware scheduling"
    - "dual techniques for scheduling on a machine with varying speed"
