human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "aligator jl a julia package for loop invariant generation"
  Abstract: We describe the Aligator.jl software package for automatically generating all polynomial invariants of the rich class of extended P-solvable loops with nested conditionals. Aligator.jl is written in the programming language Julia and is open-source. Aligator.jl transforms program loops into a system of algebraic recurrences and implements techniques from symbolic computation to solve recurrences, derive closed form solutions of loop variables and infer the ideal of polynomial invariants by variable elimination based on Grobner basis computation.

Connected through hyperedge HE-1 (induced by source paper "automatic generation of moment based invariants for prob solvable loops"):

    - "polynomial invariant generation for non deterministic recursive programs"
    - "tail probabilities for randomized program runtimes via martingales for higher moments"
