We happily bid our welcome to Mr. Raphaël Cosson, who just started his Master's research project "Algorithm Selection for Discrete Black-Box Optimization Problems" under the supervision of Prof. Dr. Carola Doerr and co-supervision of Prof. Dr. Thomas Weise. Mr. Cosson will conduct his research at the Laboratoire d'informatique de Paris 6 (LIP6) of the Sorbonne University in Paris, France during Summer 2019. His work is at the intersection of algorithm configuration, algorithm benchmarking, and the theory of optimization. As basis for his research, he will use and extend the Iterative Optimization Heuristics Profiler (IOHprofiler), an awesome tool for benchmarking and evaluating optimization algorithms, in conjunction with the tunable benchmark model developed at our group. We are looking forward to an interesting and productive collaboration.

The Institute of Applied Optimization welcomes Dr. Yan Chen [陈岩], who today has officially joined our team as researcher. Before joining our institute, he finished his PhD research at the Spatial Information Management and Modelling Department of the School of Spatial Planning of the TU Dortmund (Technische Universität Dortmund) in Germany. Dr. Chen is an expert in Geographic Information System (GIS), Remote Sensing, and Sponge City/Smart City applications as well as groundwater systems and hydrological simulations.

We are very happy that Dr. Chen joined our team. We are looking forward to working together on many interesting applications of GIS and computational intelligence.

Our team congratulates Xinlu Li [李新路], who, from today (2019-02-13) on, is Dr. Xinlu Li [李新路博士]! Earlier this year, Xinlu successfully defended his PhD thesis  "Energy-Efficient Swarm Intelligence based Routing Protocol for Wireless Sensor Networks" at the Technological University Dublin (TU Dublin) in Dublin, Ireland in front of Professor Liam Murphy from the University College Dublin (UCD) and Dr. Paul Doyle (TU Dublin). His work was co-supervised by Dr. Fred Mtenzi and Dr. Brian Keegan. Today his academic award has been approved by the Academic Council of TU Dublin. Congratulations, Dr. Li!

In the framework of his thesis, Dr. Li conducted research on Swarm Intelligence (SI) based routing for Wireless Sensor Networks (WSNs). SI is a meta-heuristic methodology used to solve numerical optimization problems by simulating swarm behaviors found in nature. These techniques demonstrate the desirable properties of interpretability, scalability, effectiveness, and robustness. There is a similarity between bio-inspired systems and routing in networks, especially in WSNs. Dr. Li designed a SI-based routing protocol capable of being deployed on large-scale WSNs to ensure efficient energy usage and prolonging the network lifetime.

On December 10, 2018, Prof. Dr. Thomas Weise received the "Second Hefei Economic and Technological Development Area Friendship Award" [第二届合肥经济技术开发区友谊奖] from the Administration Committee of the Hefei Economic and Technological Development Area [合肥经济技术开发区管理委员会]. The award was granted to eight international experts as a token of appreciation for their support and friendly cooperation for the social and economic development of the Hefei Economic and Technological Development Area (HEDTA) [经济技术开发区] in which our university is located. This award shows that the work of our team is recognized by our local government. It also shows how international and growing in importance the HEDTA is, as recipients from six different countries and three sectors (industry, research, and education) were honored.

Today, our partners from the Enterprise Application Development (EAD) group have presented our collaboration at the Project Funding Conference of the Saxon Parliament [Landtagsmittel-Projektekonferenz] at the University of Applied Sciences Zittau/Görlitz (HZG, Hochschule Zittau/Görlitz) with a cool poster. The EAD group is led by Prof. Dr. Jörg Lässig at the Faculty of Electrical Engineering and Computer Science of the HZG in Görlitz, Germany. We have a long and successful collaboration which has led to many research results. Just one year ago, Prof. Lässig and Mr. Ullrich from the EAD have visited us after Prof. Weise visited them in July. We used this visit to work on our joint topic, namely the Rigorous Performance Analysis of Algorithms. Additionally, Prof. Lässig gave a very cool short lecture on Understanding Quantum Computing. Their short stay here further directly led to two publications at the GECCO'2018 conference and to the joint organization of the International Workshop on Benchmarking of Computational Intelligence Algorithms (BOCIA) workshop this year. The poster presented at the conference also strongly refers to our joint research on Automating Scientific Research in Optimization.
