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: "yatsim an open source simulator for testing consensus based control strategies in urban traffic networks"
  Abstract: This paper presents YatSim, an open-source program for simulating consensus-based control strategies in urban traffic networks. Urban traffic is a multi-agent system which requires agreement among the agents to guarantees performance, safety, and higher efficiency. YatSim is an user-friendly program that allows to create randomized urban traffic networks in which vehicles run. Vehicles agree on crossing priorities at the intersections by executing a Consensus-Based Auction Algorithm Modified. Ccollisions are avoided by employing an onboard Model Predictive Controller.

Connected through hyperedge HE-1 (induced by source paper "traffic automation in urban road networks using consensus based auction algorithms for road intersections"):
  with members:
    - "automation of road intersections using consensus based auction algorithms"
    - "exploiting the superposition property of wireless communication for max consensus problems in multi agent systems"
