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 user s guide to zot"):
  Abstract: Zot is an agile and easily extendible bounded model checker, which can be downloaded at this http URL. The tool supports different logic languages through a multi-layered approach: its core uses PLTL, and on top of it a decidable predicative fragment of TRIO is defined. An interesting feature of Zot is its ability to support different encodings of temporal logic as SAT problems by means of plug-ins. This approach encourages experimentation, as plug-ins are expected to be quite simple, compact (usually around 500 lines of code), easily modifiable, and extendible.

Includes members:
  Member "practical automated partial verification of multi paradigm real time models":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a theory of sampling for continuous time metric temporal logic")
  Member "linear encodings of bounded ltl model checking":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "an abstraction free method for multi robot temporal logic optimal control synthesis")
