Together with our colleagues Markus Wagner, Jörg Lässig, Bin Li, and Xingyi Zhang, we are organizing a Special Issue on "Benchmarking of Computational Intelligence Algorithms" in the Applied Soft Computing (ASOC). We received quite a lot of very cool submissions until the deadline in April 2019. This is a virtual special issue, which means that the papers will immediately published when they have passed the editorial process and may appear in different physical issues and volumes of the journal. This has now happened for the first few of the submissions we have received. As a result, the journal website for our special issue is now online, too, at We still have quite a few very interesting papers in our queue, which will appear step by step on that page as well.

Second Institute Workshop on Applied Optimization


We are happy to announce that the Second Institute Workshop on Applied Optimization will be held in form of the Hefei University Operations Research and Optimization Seminar [合肥学院运筹与优化研讨会] in the conference room of the Institute of Applied Optimization on November 5, 2019. It follows the First Institute Workshop on Applied Optimization, which was still held 2018 in the meeting room near our old offices. Talks will be given by:

  • Prof. Dr. Rolf H. MÖHRING, Hefei University [合肥学院] and Technische Universtiät Berlin [柏林工业大学] ,
  • Prof. Dachuan XU [徐大川教授], Beijing University of Technology [北京工业大学] ,
  • Prof. Xiaoyan ZHANG [张晓岩教授], Nanjing Normal University [南京师范大学] ,
  • Prof. Longkun GUO [郭龙坤教授], Fuzhou University [福州大学] ,
  • Dr. Yong ZHANG, [张涌研究员], Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences [中科院深圳先进技术研究院] , and
  • Dr. Zijun WU [吴自军博士], Hefei University [合肥学院] .

我校人工智能与大数据学院将于2019年11月5日上午在中德应用优化研究所会议室召开第一次“合肥学院运筹与优化研讨会”。届时, Rolf MÖHRING教授(合肥学院,柏林工业大学)、徐大川教授(北京工业大学)、张晓岩教授(南京师范大学)、郭龙坤教授(福州大学)、张涌研究员(中科院深圳先进技术研究院)以及吴自军博士(合肥学院)等国内外运筹与优化领域专家学者将作学术报告,欢迎我校师生踊跃参加!

From October 20 to 25, 2019, our Profs. Möhring and Weise took part in the Dagstuhl Seminar 19431 with the topic Theory of Randomized Optimization Heuristics, organized by Dr. Carola Doerr (Sorbonne University, Paris, France), Carlos M. Fonseca (University of Coimbra, Portugal), Tobias Friedrich, (Hasso-Plattner-Institut, Potsdam, Germany), and Xin Yao (Southern University of Science and Technology, China). Dagstuhl Seminars are invitation-based meetings taking place in Schloss Dagstuhl, a castle located slightly remotely near the city of Wadern, Germany. The remote location is intentional: Here, researchers can meet for, say, five days, to have in-depth discussions without distractions. This is what Dagstuhl Seminars are, and we were very happy and felt honoured to be invited to attend the seminar on theory on randomized optimization heuristics. Not only did the seminar give us the chance to catch up with old friends and plan future collaborations, there we also very interesting and fruitful research discussions. I (Thomas Weise) was particularly happy to see that the topic of benchmarking and algorithm configuration also becomes more and more interesting for theoreticians. I also learned a lot about the progress that theory on optimization has made the past few years. In summary, the seminar was a very very nice event which indeed brought us one or two steps forward in our research. Many thanks to the organizers for doing such a great job!

P.S. This was a very highly productive meeting. Here, the foundations for two works were laid, as shown below. The first work is as a joint efforts of a larger group of international researchers and the second one is by our IAO team:

Today, I attended the Celebration of the 70th Anniversary of the People's Republic of China for People from all Walks of Life [壮丽70年奋斗新时代:合肥市各界人士迎国庆茶话会]. The city hall prepared a wonderful celebration in which people from entirely different careers could participate, ranging from monks and religious leaders over army officers to businessmen and researchers. Accompanied by an exhibition of calligraphy and started with ceremonial speeches, a very nice program of excellent singers and dancers was presented. Indeed, this was a very nice celebration of this important anniversary of China.

On September 19, 2019, I had the honor to take part in the Forum on Mobility of European Researchers in China taking place in the Delegation of the European Union to China [欧洲联盟驻华代表处]. About 100 researchers at all career levels and from a variety of European countries who work or study in China took part in this meeting. Currently, there are significantly more Chinese scientists contributing research in Europe than there are European researchers working in China. In this meeting, the goal therefore was to gather input about the situation of us foreign researchers in China, our success stories, the positive experiences, but also where we see opportunities for further improving conditions and raising the attractiveness of the Chinese environment for European researchers. The Delegation of the European Union will collected and compile the suggestions and ideas raised in this meeting in order to include them in a dialog between Europe and China. The goal is to increase the amount of researchers moving in both directions. Scientific exchange is of a very high importance for the advancement of research and technology – and what can better improve the exchange of ideas than the exchange of the best heads containing them?
