The Institute of Applied Optimization welcomes our new senior member Prof. Dr. Rolf H. Möhring [默里·罗尔夫]. Prof. Möhring is an outstanding and highly experienced researcher from the field of combinatorial optimization and graph algorithms who also holds positions as professor emeritus at the Fachgebiet Kombinatorische Optimierung und Graphenalgorithmen (COGA) of the Institut für Mathematik at the Technische Universität Berlin (TUB) in Berlin, Germany and as member of the Board of Directors of the Beijing Institute for Scientific and Engineering Computing (BISEC) [北京科学与工程计算研究院] of the Beijing University of Technology (BJUT) [北京工业大学] in Beijing [北京], China. He received his Diplom (equivalent to MSc), Dr. rer. nat., and Habilitation in Mathematics at the RWTH Aachen in 1973, 1975, and 1982, respectively. Before his current positions, he was assistant and associate professor at the University of Hildesheim and then at the University of Bonn, respectively.

Professor Möhring has received the Harris German-Dartmouth Distinguished Visiting Professorship of the Dartmouth College, Hanover, NH, USA, the Wissenschaftspreis der Gesellschaft für Operations Research (GOR, 2005), the Gold Medal of the Association of European Operational Research Societies (EURO, 2010), and the Honorary Professor title of the Beijing University of Technology (BJUT) in 2014.

As member of the Editorial Board, he contributes to several journals, namely Discrete Applied Mathematics, the Journal of Scheduling, Management Science, Mathematical Methods of Operations Research (MMOR), Operations Research, ORDER – A Journal on Ordered Sets and its Applications, and the SIAM Journal on Discrete Mathematics. He organized and co-organized events such as the International Conference on Operations Research (OR'94) and the International Congress of Mathematicians (ICM'98), as well as of several workshops and Dagstuhl Seminars. He also was the President of the Gesellschaft für Mathematik, Ökonomie und Operations Research (GMÖOR, 1994–1996), the Chair of the Executive Committee (1992–1995) and the President (2004–2007) of the Mathematical Programming Society (now Mathematical Optimization Society, MOS), and a member of the DFG Research Center Matheon "Mathematics for Key Technologies," where he was in charge of the Application Area "Logistics, Traffic, and Telecommunication Networks".

Prof. Möhring's research interests include graph and network algorithms, combinatorial optimization, scheduling, operations research, and their industrial applications.

After two very inspiring and productive visits in June and November 2018, we are very happy that Prof. Möhring has joined our team. We are looking forward to learn from his great expertise and to learn from his guidance.

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 warmly welcomes Mr. Lalin Heng, lecturer at the Department of Information Technology and Communication of the Institute of Technology of Cambodia (ITC) [វិទ្យាស្ថានបច្ចេកវិទ្យាកម្ពុជា] in Phnom Penh [ភ្នំពេញ], Cambodia [កម្ពុជា] for a research stay from February to March 2019. Mr. Heng has received his Master of Electrical Engineering with specialization in Information Technology in 2017 from the Gadjah Mada University, Yokyakarta, Indonesia and holds two Bachelor degrees, a Bachelor of Engineering in Computer Science also from ITC (2015) and a Bachelor of Education in TEFL from the Institute of Foreign Languages (IFL) of the Royal University of Phnom Penh (RUPP) [សាកលវិទ្យាល័យភូមិន្ទភ្នំពេញ], Phnom Penh, Cambodia (2018). He holds several professional certificates in computer networking both from Cisco and Huawei and has gathered work experience in several internships in this field, too. He has published four academic papers on routing and cell selection. The research interests of Mr. Heng include computer networks and security, which are important areas of application of optimization and computational intelligence. His work and interests are therefore closely related to the Distributed Computing research field of our institute. We are looking forward to working with Mr. Heng. Welcome to Hefei University!

Addendum: Mr. Heng has now successfully completed his stay in our team. It was a very nice and inspiring time for all of us. We enjoyed working together and exchanging ideas. We were particularly happy that we could find an intersection of Mr. Heng's interest in network security and our computational intelligence theme. As a result, we conducted a joint research project and could even publish our results at an international scientific conference:

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.
