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 "program generation for linear algebra using multiple layers of dsls"):
  Abstract: Numerical software in computational science and engineering often relies on highly-optimized building blocks from libraries such as BLAS and LAPACK, and while such libraries provide portable performance for a wide range of computing architectures, they still present limitations in terms of flexibility. We advocate a domain-specific program generator capable of producing library routines tailored to the specific needs of the application in terms of sizes, interface, and target architecture.

Includes members:
  Member "automatic generation of loop invariants for matrix operations":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "linnea automatic generation of efficient linear algebra programs")
  Member "knowledge based automatic generation of partitioned matrix expressions":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "linnea automatic generation of efficient linear algebra programs")
