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 "reconstruction of time consistent species trees"):
  Abstract: The history of gene families -- which are equivalent to event-labeled gene trees -- can to some extent be reconstructed from empirically estimated evolutionary event-relations containing pairs of orthologous, paralogous or xenologous genes. The question then arises as whether inferred event-labeled gene trees are "biologically feasible" which is the case if one can find a species tree with which the gene tree can be reconciled in a time-consistent way. #R##N#In this contribution, we consider event-labeled gene trees that contain speciation, duplication as well as horizontal gene transfer and we assume that the species tree is unknown. We provide a cubic-time algorithm to decide whether a "time-consistent" binary species for a given event-labeled gene tree exists and, in the affirmative case, to construct the species tree within the same time-complexity.
