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 "contextual equivalence for a probabilistic language with continuous random variables and recursion"):
  Abstract: We present a complete reasoning principle for contextual equivalence in an untyped probabilistic language. The language includes continuous (real-valued) random variables, conditionals, and scoring. It also includes recursion, since the standard call-by-value fixpoint combinator is expressible. We demonstrate the usability of our characterization by proving several equivalence schemas, including familiar facts from lambda calculus as well as results specific to probabilistic programming. In particular, we use it to prove that reordering the random draws in a probabilistic program preserves contextual equivalence. This allows us to show, for example, that (let x = $e_1$ in let y = $e_2$ in $e_0$) is equivalent to (let y = $e_2$ in let x = $e_1$ in $e_0$) (provided $x$ does not occur free in $e_2$ and $y$ does not occur free in $e_1$) despite the fact that $e_1$ and $e_2$ may have sampling and scoring effects.
