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 "sfcm r a novel algorithm for the hamiltonian sequence problem"):
  Abstract: A hamiltonian sequence is a path walk P that can be a hamiltonian path or hamiltonian circuit. Determining whether such hamiltonian sequence exists in a given graph is a NP-Complete problem. In this paper, a novel algorithm for hamiltonian sequence problem is proposed. The proposed algorithm assumes that $G$ have potential forbidden minors that prevent a potential hamiltonian sequence P from being a hamiltonian sequence. The algorithm's goal is to degenerate such potential forbidden minors in a two-phrase process. In first phrase, the algorithm pass through $G$ constructing a potential hamiltonian sequence $P$ with the aim of degenerating these potential forbidden minors. The algorithm, in turn, try to reconstruct P in second phrase by using a goal-oriented approach.
