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 "a new statement for selection and exception handling in imperative languages"):
  Abstract: Diverse selection statements -- if-then-else, switch and try-catch -- are commonly used in modern programming languages. To make things simple, we propose a unifying statement for selection. This statement is of the form schoose(G_1,...,G_n) where each $G_i$ is a statement. It has a a simple semantics: sequentially choose the first successful statement $G_i$ and then proceeds with executing $G_i$. Examples will be provided for this statement.

Includes members:
  Member "improving robustness via disjunctive statements in imperative programming":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "bounded choice queries for logic programming")
  Member "sequential operators in computability logic":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "fundamentals of computability logic")
