Characterising testing preorders for finite probabilistic processes

Y Deng, M Hennessy, R van Glabbeek… - Logical Methods in …, 2008 - lmcs.episciences.org
In 1992 Wang & Larsen extended the may-and must preorders of De Nicola and Hennessy
to processes featuring probabilistic as well as nondeterministic choice. They concluded with …

[HTML][HTML] On the semantics of Markov automata

Y Deng, M Hennessy - Information and Computation, 2013 - Elsevier
Markov automata describe systems in terms of events which may be nondeterministic, may
occur probabilistically, or may be subject to time delays. We define a novel notion of weak …

Testing finitary probabilistic processes

Y Deng, Y Deng - Semantics of Probabilistic Processes: An Operational …, 2014 - Springer
In this chapter we extend the results of Chap. 5 from finite to finitary processes, that is, finite-
state and finitely branching processes. Testing preorders can still be characterised as …

[HTML][HTML] A uniform framework for modeling nondeterministic, probabilistic, stochastic, or mixed processes and their behavioral equivalences

M Bernardo, R De Nicola, M Loreti - Information and Computation, 2013 - Elsevier
Labeled transition systems are typically used as behavioral models of concurrent processes.
Their labeled transitions define a one-step state-to-state reachability relation. This model …

Open bisimulation for quantum processes

Y Deng, Y Feng - IFIP International Conference on Theoretical Computer …, 2012 - Springer
Quantum processes describe concurrent communicating systems that may involve quantum
information. We propose a notion of open bisimulation for quantum processes and show that …

Data races and static analysis for interrupt-driven kernels

N Chopra, R Pai, D D'Souza - … on Programming, ESOP 2019, Held as Part …, 2019 - Springer
We consider a class of interrupt-driven programs that model the kernel API libraries of some
popular real-time embedded operating systems and the synchronization mechanisms they …

Logical, metric, and algorithmic characterisations of probabilistic bisimulation

Y Deng, W Du - arXiv preprint arXiv:1103.4577, 2011 - arxiv.org
Many behavioural equivalences or preorders for probabilistic processes involve a lifting
operation that turns a relation on states into a relation on distributions of states. We show …

Revisiting trace and testing equivalences for nondeterministic and probabilistic processes

M Bernardo, R De Nicola… - Logical Methods in …, 2014 - lmcs.episciences.org
Two of the most studied extensions of trace and testing equivalences to nondeterministic
and probabilistic processes induce distinctions that have been questioned and lack …

Probabilistic Trace and Testing Semantics: The Importance of Being Coherent

M Bernardo - Foundations and Trends® in Programming …, 2022 - nowpublishers.com
It is well known that trace and testing semantics over nondeterministic and probabilistic
processes are influenced by the class of schedulers used to resolve nondeterministic …

Coherent resolutions of nondeterminism

M Bernardo - … Engineering: 16th European Workshop, EPEW 2019 …, 2020 - Springer
We study the impact that different ways of resolving nondeterminism within probabilistic
automata have on the properties of probabilistic behavioral equivalences. Firstly, we provide …
