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 "randomly coloring graphs of bounded treewidth"):
  Abstract: We consider the problem of sampling a proper $k$-coloring of a graph of maximal degree $\Delta$ uniformly at random. We describe a new Markov chain for sampling colorings, and show that it mixes rapidly on graphs of bounded treewidth if $k\geq(1+\epsilon)\Delta$, for any $\epsilon>0$.

Includes members:
  Member "rapidly mixing markov chains a comparison of techniques a survey":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "mix and match markov chains mixing times for matching in rideshare")
  Member "an fptas for counting proper four colorings on cubic graphs":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "counting independent sets and colorings on random regular bipartite graphs")
  Member "random cluster dynamics for the ising model is rapidly mixing":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "lower bounds for testing graphical models colorings and antiferromagnetic ising models")
  Member "sparsest cut on bounded treewidth graphs algorithms and hardness results":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "on the parameterized complexity of sparsest cut and small set expansion problems")
  Member "known algorithms on graphs of bounded treewidth are probably optimal":
    also connected through other hyperedges:
