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 "weaker consistency notions for all the csps of bounded width"):
  Abstract: The characterization of all the Constraint Satisfaction Problems of bounded width, proposed by Feder and Vardi [SICOMP'98], was confirmed in [Bulatov'09] and independently in [FOCS'09, JACM'14]. Both proofs are based on the (2,3)-consistency (using Prague consistency in [FOCS'09], directly in [Bulatov'09]) which is costly to verify. #R##N#We introduce a new consistency notion, Singleton Linear Arc Consistency (SLAC), and show that it solves the same family of problems. SLAC is weaker than Singleton Arc Consistency (SAC) and thus the result answers the question from [JLC'13] by showing that SAC solves all the problems of bounded width. At the same time the problem of verifying weaker consistency (even SAC) offers significant computational advantages over the problem of verifying (2,3)-consistency which improves the algorithms solving the CSPs of bounded width.
