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 "directed multicut with linearly ordered terminals"):
  Abstract: Motivated by an application in network security, we investigate the following “linear” case of Directed Multicut. Let G be a directed graph which includes some distinguished vertices t1,...,tk. What is the size of the smallest edge cut which eliminates all paths from ti to tj for all i < j? We show that this problem is fixed-parameter tractable when parametrized in the cutset size p via an algorithm running in O(4 p pn 4 ) time.

Includes members:
  Member "fixed parameter tractability of multicut in directed acyclic graphs":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a relaxation of the directed disjoint paths problem a global congestion metric helps")
  Member "fixed parameter tractability of directed multiway cut parameterized by the size of the cutset":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "hitting long directed cycles is fixed parameter tractable")
  Member "multicut is fpt":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "parameterized inapproximability for steiner orientation by gap amplification")
  Member "fixed parameter tractability of multicut parameterized by the size of the cutset":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "the computational complexity of finding temporal paths under waiting time constraints")
