Simon Anderer successfully defended his PhD with the title:

Role Mining for Industrial-strength ERP Systems Using Evolutionary Algorithms

 A new DFG project which is jointly financed by the Austrian Science Fund (FWF) has been approved. We will collaborate with the Johannes Kepler University in Linz and the German Aerospace Center (DLR) in Oberpfaffenhofen. The goal of the project is the use of autonomous drone swarms for rescue applications. Here, drones can imitate the swarming behavior of birds to always have an optimal view for rescue purposes. 

Considering the current high level of attention that is being paid to drones, it is easy to overlook the enormous potential that they bring with them in civilian areas. Drone groups are establishing themselves worldwide in blue light organizations such as the police, fire brigade and mountain rescue to use this technology to save human lives. Search and rescue operations benefit, among other things, from the flexible, fast and - compared to helicopters - inexpensive and safe use of drones. They are also used in the inspection of disaster areas, for the early detection of forest fires, for border security, or wildlife observation. The problem with all these applications is always the occlusion caused by vegetation, such as forest, which usually makes it impossible to find, detect, and track people, animals or vehicles in single aerial photographs. This project is based on the "Airborne Optical Sectioning" (AOS) imaging method developed at the Johannes Kepler University and will study further potentials of the swarms. 

On 6th February, Jens Weise successfully defended his PhD with the title "Evolutionary Many-Objective Optimisation for Pathfinding Problems":

On Monday 6th February, Prof. Kalyanmoy Deb from Michigan State University gave a University Guest lecture with the Title "Evolutionary Multi-Criterion Optimization: An Emerging Computational Problem-Solving Tool". Over 100 participants attended the talk.

Abstract: Most problems in science, engineering and commerce involve more than one conflicting criteria to be simultaneously optimized. Despite the vast literature on scalarizing multiple criteria into one, evolutionary optimization methods of treating them as truly multi-criterion problems in a Pareto sense produce a number of additional benefits to the users. Their ability to find and maintain multiple trade-off solutions with a flexible and customizable framework provides vital knowledge about the problem in addition to the optimal solutions themselves. In this lecture, we shall present a few popular and state-of-the-art algorithms, demonstrate their advantages on a number of real-world practical problems from engineering and society, and introduce some recent research topics. Additionally, the use of machine learning algorithms and human knowledge in enhancing their performance, and the use of multi-criterion algorithms in enhancing performance of machine learning methods will be discussed.

Diesjährige Wettkampferfolge des Team robOTTO der Otto-von Guericke-Universität Magdeburg

Am 28. und 29.07.2022 fanden neben den MINT Mach-Aktionstage der Landeshauptstadt Magdeburg in der Festung Mark die GermanOpen (Europameisterschaft) der RoboCup@Work-Liga statt. Sieben RoboCup-Teams u.a. aus Deutschland und Österreich ließen ihre Roboter im freundschaftlichen Wettkampf gegeneinander antreten. Organisiert wurde die Veranstaltung in diesem Jahr vom Team robOTTO der Otto-von Guericke-Universität Magdeburg. Besonderes Highlight stellte das Veranstaltungsformat dar, welches in diesem Jahr sowohl in Präsenz als auch in digitaler Form durchgeführt wurde. So nahm zum Beispiel das griechische RoboCup-Team DIR digital an der Veranstaltung teil, indem Sie ihre Läufe in einer eigenen Wettkampfarena streamten. Die Schiedsrichter bewerteten sodann aus der Fern die erledigten Aufgaben. Innerhalb der fünf anwesenden Teams erreichte das Team robOTTO den dritten Platz.

Die GermanOpen stellten auch in diesem Jahr für viele europäischen Teams eine Generalprobe für die einige Wochen später stattfindende Weltmeisterschaft – dem RoboCup dar. In diesem Jahr fand dieser bereits zwei Wochen nach den GermanOpen vom 11. – 17.07. 2022 in Bangkok (Thailand) statt. 

Das Team der Otto-von-Guericke-Universität reiste mit insgesamt sieben Teammitglieder:innen und ihrem Roboter „Euler“ nach Bangkok. Die Zeit zwischen den Wettkämpfen wurde vom Team intensiv genutzt um Soft- und Hardware-Bugs zu fixen. Die harte Vorbereitung sollte sich in einem spannenden Kopf-an-Kopf-Rennen im Finale in Bangkok auszahlen. So errang das Team stolz den Vizeweltmeister-Titel und setzte seine Erfolge der letzten Jahre fort. Es zweigte sich deutlich, dass sich das Team vor allem softwaretechnisch gegen die Konkurrenz durchsetzen konnte. Ziel für die nächste Wettkampfsaison ist die Optimierung der Hardware des Roboters, um, so hoffte das Team, bei der Weltmeisterschaft 2023 in Bordeaux (Frankreich) den Weltmeistertitel mit nach Hause zu bringen.

Neben der jahrelangen erfolgreichen Teilnahme am RoboCup, hat das Team robOTTO eine tragende Rolle in der RoboCup@Work-Liga. So sind die Teammitglieder:innen in verschieden Rollen sowohl auf nationaler als auch internationaler Ebene an der Organisation der RoboCup-Wettkämpfe beteiligt, vertreten die Co-Leitung der Liga und sind darüber hinaus auch an der Weiterentwicklung der Regeln und der Liga selbst beteiligt.

Das Team robOTTO ist interdisziplinär aufgestellt und gibt den Studierenden aller Fakultäten die Möglichkeit an und mit Robotern zu arbeiten. Ziel ist es dabei die Leidenschaft für die Robotik aufleben zu lassen und für Skills auf- und auszubauen, die in der Arbeitswelt gefragt sind. In diesem Rahmen bietet das Team den Studierenden der Otto-von-Guericke-Universität Magdeburg an nachhaltige Forschungs-, Bachelor- und Masterarbeiten sowie Softwareprojekte umzusetzen.

Interessenten können gern über robotto@ovgu.de Kontakt mit dem Team aufnehmen.

We will start a new DFG project "Optimization of Gas-Solid Fluidized Beds Operation using Machine Learning" in collaboration with Prof. Berend vam Wachem Chair of Mechanical Process Engineering at OVGU.

Fluidized beds are the basis for scores of applications in which fast mixing, heat and mass transfer of gas and solid particles are essential. Their performance largely relies on the bubble dynamics: rising bubbles drive the solids circulation and significantly enhance gas-solids contact, improving mixing, reactions, and transport properties. So far, almost all fluidized beds are operated with a uniform gas flow. However, some recent academic work shows that operating a fluidized bed with an alternating gas flow (e.g. sinusoidal gas fluidisation velocity) leads to different bubble patterns and dynamics. In this project, we aim to control the bubbles in a fluidized bed, by application of computational intelligence (CI) methodologies such as evolutionary algorithms and genetic programming. We will use our lab-scale fluidized bed with camera system and our model developments in the Eulerian-Eulerian and Eulerian-Lagrangian frameworks to capture the dynamics of bubbles in the fluidized bed as the fluidizing gas velocity is spatio-temporally varied. Firstly, these results will be used to find the optimal inflow-pattern for given target functions. The challenge for the CI algorithm is to find the right balance between the computationally and timely intensive experimental data and the simulation data to efficiently deliver the required fluidization velocity profile. In addition, we aim to address multiple conflicting target functions using multi-objective optimization algorithms. Secondly, the CI algorithm will be used to steer and control the velocity profile, to obtain a specified bubble size and dynamics. Being able to control the behavior of the bubbles in a fluidized bed will significantly improve the desired outcome, such as product quality, efficiency and selectivity of the process, to name a few.

On first of July, we started a new project funded by BMBF:
