human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge groups authors who co-authored the same paper.

Details of the hypergraph:
Center hyperedge (induced by source paper "Planning via Model Checking: A Decision Procedure for AR"):
  Abstract: In this paper we propose a new approach to planning based on a “high level action language”, called AR, and “model checking”. AR is an expressive formalism which is able to handle, among other things, ramifications and non-deterministic effects. We define a decision procedure for planning in AR which is based on “symbolic model checking”, a technique which has been successfully applied in hardware and software verification. The decision procedure always terminates with an optimal solution or with failure if no solution exists. We have constructed a planner, called MBP, which implements the decision procedure.
