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 "the complexity of proving that a graph is ramsey"):
  Abstract: We say that a graph with $n$ vertices is $c$-Ramsey if it does not contain either a clique or an independent set of size $c \log n$. We define a CNF formula which expresses this property for a graph $G$. We show a superpolynomial lower bound on the length of resolution proofs that $G$ is $c$-Ramsey, for every graph $G$. Our proof makes use of the fact that every Ramsey graph must contain a large subgraph with some of the statistical properties of the random graph.

Includes members:
  Member "clause learning algorithms with many restarts and bounded width resolution":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "towards a complexity theoretic understanding of restarts in sat solvers")
  Member "linear logic based analysis of constraint handling rules with disjunction":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "constraint handling rules what else")
