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 "needed computations shortcutting needed steps"):
  Abstract: We define a compilation scheme for a constructor-based, strongly-sequential, graph rewriting system which shortcuts some needed steps. The object code is another constructor-based graph rewriting system. This system is normalizing for the original system when using an innermost strategy. Consequently, the object code can be easily implemented by eager functions in a variety of programming languages. We modify this object code in a way that avoids total or partial construction of the contracta of some needed steps of a computation. When computing normal forms in this way, both memory consumption and execution time are reduced compared to ordinary rewriting computations in the original system.

Includes members:
  Member "rewriting and narrowing for constructor systems with call time choice semantics":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "singular and plural functions for functional logic programming")
  Member "on the correctness of pull tabbing":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "making bubbling practical")
