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 the equivalence among problems of bounded width"):
  Abstract: In this paper, we introduce a methodology, called decomposition-based reductions, for showing the equivalence among various problems of bounded-width. #R##N#First, we show that the following are equivalent for any $\alpha > 0$: #R##N#* SAT can be solved in $O^*(2^{\alpha \mathrm{tw}})$ time, #R##N#* 3-SAT can be solved in $O^*(2^{\alpha \mathrm{tw}})$ time, #R##N#* Max 2-SAT can be solved in $O^*(2^{\alpha \mathrm{tw}})$ time, #R##N#* Independent Set can be solved in $O^*(2^{\alpha \mathrm{tw}})$ time, and #R##N#* Independent Set can be solved in $O^*(2^{\alpha \mathrm{cw}})$ time, where tw and cw are the tree-width and clique-width of the instance, respectively. #R##N#Then, we introduce a new parameterized complexity class EPNL, which includes Set Cover and Directed Hamiltonicity, and show that SAT, 3-SAT, Max 2-SAT, and Independent Set parameterized by path-width are EPNL-complete. This implies that if one of these EPNL-complete problems can be solved in $O^*(c^k)$ time, then any problem in EPNL can be solved in $O^*(c^k)$ time.
