Ideal Abstractions for Well-Structured Transition Systems [chapter]

Damien Zufferey, Thomas Wies, Thomas A. Henzinger
2012 Lecture Notes in Computer Science  
Many infinite state systems can be seen as well-structured transition systems (WSTS), i.e., systems equipped with a well-quasi-ordering on states that is also a simulation relation.  ...  Our analysis is an abstract interpretation whose abstract domain builds on the ideal completion of the well-quasi-ordered state space, and a widening operator that mimics acceleration and controls the  ...  Conclusion We proposed a novel abstract interpretation framework to compute precise approximations of the covering set of WSTS.  ...

Well-abstracted transition systems: application to FIFO automata

Alain Finkel, S. Purushothaman Iyer, Grégoire Sutre
2003 Information and Computation  
We propose the use of abstractions as a general framework to design accelerations. We investigate SemiLinear Regular Expressions (SLREs) as symbolic representations for FIFO automata.  ...  In the case of infinite state systems, there has been a great deal of interest in accelerations -a technique for characterizing the result of iterating an execution sequence an arbitrary number of times  ...  version of Well-Abstracted Transition Systems published in CONCURÕ2000 proceedings.  ...

Infinite-State Liveness-to-Safety via Implicit Abstraction and Well-Founded Relations [chapter]

Jakub Daniel, Alessandro Cimatti, Alberto Griggio, Stefano Tonetta, Sergio Mover
2016 Lecture Notes in Computer Science  
We present a fully-symbolic LTL model checking approach for infinite-state transition systems.  ...  The algorithm iterates by attempting to remove spurious abstract fair loops: either it finds new predicates, to avoid spurious abstract prefixes, or it introduces new well-founded relations, based on the  ...  Once the abstract transition relation is computed, any algorithm for finite-state systems can be applied.  ...
