The paper entitled “Automated Fine Tuning of Probabilistic Self-Stabilizing Algorithms” by Saba Aflaki, Matthias Volk, Borzoo Bonakdarpour, Joost-Pieter Katoen and Arne Storjohann has been accepted at SRDS 2017 in Hongkong. The paper presents automated techniques to find the probability distribution that achieves minimum average recovery time for randomized distributed self-stabilizing algorithms.
The paper entitled “Model-Based Safety Analysis of Vehicle Guidance Systems” by Majdi Ghadhab, Sebastian Junges, Joost-Pieter Katoen, Matthias Kuntz and Matthias Volk, has been accepted at SafeComp 2017. The paper emerged from a co-operation with BMW and presents a model-based approach towards the safety analysis of vehicle guidance systems by comparing different mappings from functional […]
We are looking for enthusiastic and highly qualified doctoral researchers. 12 positions are available within the Research Training Group (RTG) UnRAVeL. The key emphasis of an RTG is on the qualification of doctoral researchers with a focused research program and a structured training strategy. UnRAVeL aims to significantly advance probabilistic modelling and analysis for uncertainty […]
The MOVES group proudly announces that Professor Joost-Pieter Katoen has received the “FAMOS für Familie” price by RWTH Aachen University. Based on nominations by employees, it is yearly awarded to management personnel at our university. Its aim is to acknowledge particular effort for family-friendly working conditions, sustainable team leadership, and creative solutions to staff management. […]
The paper “Fast Dynamic Fault Tree Analysis by Model Checking Techniques” by Matthias Volk, Sebastian Junges, and Joost-Pieter Katoen has been accepted to IEEE Transactions on Industrial Informatics. The paper presents a novel state-space generation technique for DFTs and combines this with a simple, though very effective, abstraction.
The German Research Council (DFG) has granted our proposal to launch a Research Training Group on “Uncertainty and Randomness in Algorithms, Verification and Logic” (UnRAVeL). It funds 15 Ph.D. positions over a period of 4,5 years to work on challenging foundational research questions to treat uncertainty. The project involves 12 research groups from theoretical computer […]
The papers “A Storm is Coming: A Modern Probabilistic Model Checker” by Christian Dehnert, Sebastian Junges, Joost-Pieter Katoen and Matthias Volk and “Markov Automata with Multiple Objectives” by Tim Quatmann, Sebastian Junges and Joost-Pieter Katoen have been accepted at CAV 2017. The first paper presents the new and powerful probabilistic model checker storm, whereas the […]
The MOVES group proudly announces that Professor Joost-Pieter Katoen has received a Honorary Doctorate from Aalborg University, Denmark. He was awarded for his distinguished efforts in the field of Computer Science, in particular Computer-Aided Verification. The (Danish) laudation can be found here.
The paper “A Weakest Pre-Expectation Semantics for Mixed-Sign Expectations” by Benjamin L. Kaminski and Joost-Pieter Katoen has been accepted to LICS 2017. The paper presents a wp–style calculus for reasoning about the expected values of mixed–sign unbounded random variables after execution of a probabilistic program.
We launch the new probabilistic model checker Storm. It features the analysis of discrete- and continuous-time variants of both Markov chains and MDPs. It supports the Prism and JANI modeling languages, probabilistic programs, dynamic fault trees and generalized stochastic Petri nets. It has a modular set-up in which solvers and symbolic engines can easily be […]
