Bertazzi, A. (author)This thesis studies methods to improve the applicability and the performance of Markov Chain Monte Carlo (MCMC) algorithms based on Piecewise Deterministic Markov processes (PDMPs). First, we discuss the key ideas that lay the foundations of the field of MCMC, spanning from the Metropolis-Hastings algorithm to PDMC methods, emphasising a common...doctoral thesis 2023

Burgers, Nienke (author)The real-life Vehicle Routing Problem (VRP) is the problem in which a set of vehicles needs to perform a set of tasks such that we have a shortest total driving distance. Such problems can be solved using construction algorithms. Finding the best-performing construction algorithm is time-consuming because these algorithms consist of many...master thesis 2023

Zwetsloot, Eva (author)In multi-agent systems reaching consensus has been a long-standing problem. A considerable amount of research has been focused on how event-triggered consensus can be used to limit the energy consumption of the communication system while still ensuring convergence to the neighbourhood of a point or a formation. These algorithms rely on having...master thesis 2023

Benist, Bram (author)This master thesis introduces Hierarchical Active Inference Control (HAIC) as a control method for nonholonomic systems. This method only requires tuning of a minimal number of hyperparameters and has a relative low computation load. HAIC is based on recent research done in the application of the neuroscientific theory of Active Inference for...master thesis 2023

Mulder, Joas (author)Deformable Image Registration (DIR) is a medical imaging process involving the spatial alignment of two or more images using a transformation model that can account for non-rigid deformations. B-spline-based transformation models have emerged as a common approach to express such spatial alignments. However, without additional measures, their...master thesis 2023

van den Berg, Rob (author)The problem of finding a target and forming a path to it is known and is well-explored in the field of swarm robotics. Using swarm intelligence, even swarms of simple robots are capable of solving this problem. However, often these works assume that two robots can perceive each other can physically reach each other, or that robots can detect any...master thesis 2023

Bouter, P.A. (author)In recent years, the use of Artificial Intelligence (AI) has become prevalent in a large number of societally relevant, real-world problems, e.g., in the domains of engineering and health care. The field of Evolutionary Computation (EC) can be considered to be a sub-field of AI, concerning optimization using Evolutionary Algorithms (EAs), which...doctoral thesis 2023

Blaha, Till (author)An effective distribution of flight control commands over many aircraft actuators (engines, control surfaces, flaps, etc.) can be achieved with constrained optimisation. Active-Set methods solve these problems efficiently, but their computational time requirements are still prohibitive for aircraft with many actuators or slower digital flight...master thesis 2023

Zeng, Henwei (author)Several algorithms can often be used to solve a complex problem, such as the SAT problem or the graph coloring problem. Those algorithms differ in terms of speed based on the size or other features of the problem. Some algorithms perform much faster on a small size while others perform noticeably better on a larger instance. The optimization...bachelor thesis 2023

Yuan, S. (author), Reniers, G.L.L.M.E. (author), Yang, M. (author), Bai, Y. (author)Chemical plants face safety hazards and security threats that may induce catastrophic scenarios. Safety and security barriers are employed widely to protect chemical plants from accidental and intentional undesired events and mitigate consequences. Managing safety and security barriers effectively and economically is a research topic with...journal article 2023

Driebergen, Tim (author)The minimum vertex cover problem (MinVertexCover) is an important optimization problem in graph theory, with applications in numerous fields outside of mathematics. As MinVertexCover is an NP-hard problem, there currently exists no efficient algorithm to find an optimal solution on arbitrary graphs. We consider quantum optimization algorithms,...master thesis 2023

Tsaniklidis, Georgios (author)Nowadays, the high demand for road transportation often reaches a point where it exceeds the capacity of freeway traffic networks, resulting in congestion. Freeway traffic congestion is a major social problem, as it is the reason for increased time delays, higher accident risk and environmental pollution. There is, therefore, the need for a...master thesis 2023

Belgioioso, Giuseppe (author), Grammatico, S. (author)We address the generalized Nash equilibrium seeking problem for a population of agents playing aggregative games with affine coupling constraints. We focus on semi-decentralized communication architectures, where there is a central coordinator able to gather and broadcast signals of aggregative nature to the agents. By exploiting the...journal article 2023

Mehravar, Soroosh (author), Razavi-Termeh, Seyed Vahid (author), Moghimi, Armin (author), Ranjgar, Babak (author), Foroughnia, Fatemeh (author), Amani, Meisam (author)Flood has long been known as one of the most catastrophic natural hazards worldwide. Mapping flood-prone areas is an important part of flood disaster management. In this study, a flood susceptibility mapping framework was developed based on a novel integration of nature-inspired algorithms into support vector regression (SVR). To this end,...journal article 2023

Gao, Mingyu (author), Chakraborty, S.S. (author), Kulahcioglu Ozkan, Burcu (author)The Probabilistic Concurrency Testing (PCT) algorithm that provides theoretical guarantees on the probability of detecting concurrency bugs does not apply to weak memory programs. The PCT algorithm builds on the interleaving semantics of sequential consistency, which does not hold for weak memory concurrency. It is because weak memory...conference paper 2023
