Verification of Concurrent Programs Using Petri Net Unfoldingsroblem for an abstraction of the concurrent program through a Petri net (a problem which can be solved using McMillan’s unfoldings technique). We present a method of abstraction refinement which translates Floyd/Hoare-style proofs for sample traces into additional synchronization constraints for the

Eliminating Message Counters in Synchronous Threshold Automatad a verification method based on bounded model checking. Modeling a distributed algorithm by a threshold automaton requires to correctly deal with the semantics for sending and receiving messages based on the fault assumption. This step was done manually so far, and required human ingenuity. Motivat

A Reduction Theorem for Randomized Distributed Algorithms Under Weak Adversariesproofs for distributed algorithms, and express the property that the adversary (scheduler), which has to decide which messages to deliver to which process, has no means of inferring the outcome of random choices, and the content of the messages..n this paper, we introduce a model for randomized dist

Twinning Automata and Regular Expressions for String Static Analysisutomata. The main novelty of . is that it works over an alphabet of strings instead of single characters. On the one hand, such an approach requires a more complex and refined definition of the widening operator, and the abstract semantics of string operators. On the other hand, it is in position to

Syntax-Guided Synthesis for Lemma Generation in Hardware Model Checkinge model checking is moving from bit-level to word-level problems, and it is expected that model checkers can benefit when such high-level information is available. However, for bit-vectors, it is challenging to find a good word-level interpolation strategy for lemma generation, which hinders the use

The conference was planned to take place in Copenhagen, Denmark, but changed to an online event due to the COVID-19 pandemic. .The 23 papers presented in this volume were carefully reviewed from 48 submissions.

Twinning Automata and Regular Expressions for String Static Analysis obtain strictly more precise results than state-of-the-art approaches. We implemented a prototype of ., and we applied it to some case studies taken from some of the most popular Java libraries manipulating string values. The experimental results confirm that . is in position to obtain strictly more precise results than existing analyses.
