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 "on minimum connecting transition sets in graphs"):
  Abstract: A forbidden transition graph is a graph defined together with a set of permitted transitions i.e. unordered pair of adjacent edges that one may use consecutively in a walk in the graph. In this paper, we look for the smallest set of transitions needed to be able to go from any vertex of the given graph to any other. We prove that this problem is NP-hard and study approximation algorithms. We develop theoretical tools that help to study this problem.

Includes members:
  Member "shortest paths avoiding forbidden subpaths":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "connecting edge colouring")
  Member "properly coloured cycles and paths results and open problems":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "connecting edge colouring")
