The analysis of complex distributed systems requires dedicated software tools. The mCRL
language and toolset have been developed to support such analysis. We highlight changes …

Abstract Model checking is a technique for automatically assessing the quality of software
and hardware systems and designs. Given a formalisation of both the system behaviour and …

In model checking, reduction techniques can be helpful tools to fight the state-space
explosion problem. Partial-order reduction (POR) is a well-known example, and many POR …

We present a sound static analysis technique for fighting the combinatorial explosion of
parameterised Boolean equation systems (PBESs). These essentially are systems of …

Parameterised Boolean Equation Systems (PBESs) are sequences of Boolean fixed point
equations with data variables, used for, eg, verification of modal mu-calculus formulae for …

Model checking is a technique to automatically assess whether a model of the behaviour of
a system meets its requirements. Evidence explaining why the behaviour does (not) meet its …

Abstract Parameterised Boolean Equation Systems (PBESs) can be used to represent many
different kinds of decision problems. Most notably, model checking and equivalence …

Process algebras are used to study the behaviour of parallel systems. The mCRL2 toolset
has been designed to analyse process algebraic models of such systems. Given that almost …

We present a symmetrical protocol to repeatedly negotiate a desired service level between
two parties, where the service levels are taken from some totally ordered finite domain. The …

We present a theory of abstraction for the framework of parameterised Boolean equation
systems, a first-order fixpoint logic. Parameterised Boolean equation systems can be used to …
