Verifying nondeterministic probabilistic channel systems against ω-regular linear-time properties

Christel Baier, Nathalie Bertrand, Philippe Schnoebelen
2007 ACM Transactions on Computational Logic  
Lossy channel systems (LCSs) are systems of finite state automata that communicate via unreliable unbounded fifo channels.  ...  While all variants of the qualitative LTL model checking problem for the full class of history-dependent schedulers are undecidable, the same questions for finite-memory scheduler can be solved algorithmically  ...  from interpretations of probabilistic lossy channel systems by Markov chains.  ...

Formal analysis techniques for gossiping protocols

Rena Bakhshi, Francois Bonnet, Wan Fokkink, Boudewijn Haverkort
2007 ACM SIGOPS Operating Systems Review  
We present properties of interest for gossiping protocols and discuss how various formal evaluation techniques can be employed to predict them.  ...  We give a survey of formal verification techniques that can be used to corroborate existing experimental results for gossiping protocols in a rigorous manner.  ...  Schnoebelen [67] surveyed several proposals for modelling probabilistic lossy channel systems with Markov chains and the verification techniques they support.  ...

Symbolic Verification of Communicating Systems with Probabilistic Message Losses: Liveness and Fairness [chapter]

C. Baier, N. Bertrand, Ph. Schnoebelen
2006 Lecture Notes in Computer Science  
NPLCS's are a new model for nondeterministic channel systems where unreliable communication is modeled by probabilistic message losses.  ...  We show that, for ω-regular linear-time properties and finite-memory schedulers, qualitative model-checking is decidable.  ...  For eventually properties with the satisfaction criteria "with positive probability", decidability relies on the computation of iterative predecessors in (non-probabilistic) lossy channel systems: For  ...

2012 Formal methods in system design  
This has immediate applications for the verification of wellstructured systems, where a main issue is the computability of fixpoint expressions, and in particular for game-theoretical properties and probabilistic  ...  systems where nesting and alternation of least and greatest fixpoints are common.  ...  Probabilistic lossy channel systems Our general finite convergence theorem has applications to qualitative probabilistic modelchecking problems for well-structured transition systems.  ...

Epidemic algorithms for reliable content-based publish-subscribe: an evaluation

P. Costa, M. Migliavacca, G.P. Picco, G. Cugola
2004 24th International Conference on Distributed Computing Systems, 2004. Proceedings.  
In this paper, we evaluate the effectiveness of an approach based on epidemic algorithms.  ...  Nevertheless, currently available systems usually do not provide reliability guarantees, which hampers their use in dynamic and unreliable scenarios, notably including mobile ones.  ...  Independently from the scheme adopted, the probabilistic and decentralized nature of epidemic algorithms yields a number of desirable properties.  ...

Information processing in living systems [article]

2014 arXiv   pre-print
Many of these analyses are motivated by the idea that biological systems may have evolved to optimize the gathering and representation of information, and we review the experimental evidence for this optimization  ...  Systems of interest range from single molecules (the sequence diversity in families of proteins) to groups of organisms (the distribution of velocities in flocks of birds), and all scales in between.  ...  Acknowledgments We thank our many collaborators and colleagues, whose names appear in the references, for teaching us so much and for making the exploration of these ideas so pleasurable.  ...
