Abstract The eXtensible Access Control Markup Language (XACML) is an extensible and
flexible XML language for the specification of access control policies. However, the richness …

Good tools can bring mechanical verification to programs written in mainstream functional
languages. We use hs-to-coq to translate significant portions of Haskell's containers library …

Abstract The eXtensible Access Control Markup Language (XACML) has attracted
significant attention from both industry and academia, and has become the de facto standard …

Formal development in Event-B generally requires the validation of a large number of proof
obligations. Some automatic tools exist to automatically discharge a significant part of them …

We consider the problem of deciding the theory of finite sets with cardinality constraints
using a satisfiability modulo theories solver. Sets are a common high-level data structure …

We present an integration of the constraint solving kernel of the ProB model checker with the
SMT solver Z3. We apply the combined solver to B and Event-B predicates, featuring higher …

In this paper we present a solver for a first-order logic language where sets and binary
relations can be freely and naturally combined. The language can express, at least, any full …

Symbolic execution tools query constraint solvers for tasks such as determining the
feasibility of program paths. Therefore, the effectiveness of such tools depends on their …

Formal development in Event-B generally requires the validation of a large number of proof
obligations. Some tools automatically discharge a significant part of them, thus augmenting …

An ongoing challenge for computer science is the development of a tool which automatically
verifies programs meet their specifications, and are free from runtime errors such as divide …
