A comparison of Presburger engines for EFSM reachability [chapter]

Thomas R. Shiple, James H. Kukula, Rajeev K. Ranjan
1998 Lecture Notes in Computer Science  
We compare the performance of two Presburger packages, the automata-based Shasta package and the polyhedrabased Omega package.  ...  While the raw speed of each of these two packages can be superior to the other by a factor of 50 or more, we found the asymptotic performance of Shasta to be equal or superior to that of Omega for the  ...  Acknowledgments We thank Kurt Keutzer for suggesting to us the use of Presburger arithmetic for analyzing EFSMs, and Adnan Aziz for modifying VIS to support EFSMs.  ...

Homer: A Higher-Order Observational Equivalence Model checkER [chapter]

David Hopkins, C. -H. Luke Ong
2009 Lecture Notes in Computer Science  
It works by first translating terms of the fragment into a precise representation of their game semantics as visibly pushdown automata (VPA).  ...  To the best of our knowledge, HOMER is the first implementation of a model checker of 3rd-order programs.  ...  Visibly Pushdown Automata The visibly pushdown automata (VPA) [3] are a subclass of pushdown automata in which the stack actions (push, pop or no-op) are completely determined by the input symbol.  ...
