From October 18 to 27, 2017, our Master's Student Ms. Qi Qi [齐琪] of the University of Science and Technology of China (USTC) [中国科学技术大学] conducted an invited research stay at the Chair of System Simulation of the Department of Informatics of the Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) in Erlangen, Germany.

The Chair for System Simulation performs research on the modeling and efficient simulation and optimization of complex systems in science and engineering. Its focus is on the design and the analysis of algorithms and tools for these purposes. Since most simulations of complex systems are computationally heavy, the work of the group therefore is centered around diverse high-performance computation (HPC) techniques. They

  • research HPC models, by developing tailored simulation algorithms for physical applications, three phase and thermal free flows based on the lattice Boltzmann method, and multi-level algorithms,
  • research scientific computing, by researching computational optics, numerical analysis, and related HPC methods, and
  • develop HPC software, including visualisations of simulation results, a framework for simulation of fluid scenarios based on the Lattice Boltzmann, and software for rigid body dynamics

Ms. Qi was invited by of Prof. Dr. Harald Köstler, whose main research interest is on the latter point. He works on the ExaStencils project for Advanced Stencil-Code Engineering. Stencil codes are compute-intensive algorithms in which data points in a grid are redefined repeatedly as a combination of the values of neighboring points. The neighborhood pattern used is called a stencil. Stencil codes are used for the solution of discrete partial differential equations and the resulting linear systems.

On Wednesday, October 25, 2017 from 09:30 to 10:20, I presented my research talk "Automating Scientific Research in Optimization" in Anhui University (AHU) [安徽大学], Conference Hall on the First Floor below of the Xingzhi Building [安徽大学磬苑校区行知楼负一楼报告厅] at the Symposium on Evolutionary Computation [进化计算领域专家系列学术报告会] under the organization of Professors Xingyi Zhang (Anhui University) and Bin Li (USTC) for the IEEE CIS Hefei Chapter. The talk followed the presentation "Approximation-Guided Many-Objective Optimisation and the Travelling Thief Problem" by our guest researcher Dr. Markus Wagner, Senior Lecturer from the Optimisation and Logistics Group of the School of Computer Science of The University of Adelaide, Australia and, in turn, was followed by the talk "Species-based PSO for Continuous Dynamic Constrained Optimization" by Associate Prof. Dr. Wenjian Luo (USTC). All talks are open for any interested audience. [poster, slides]

Our institute welcomes Dr. Markus Wagner, Senior Lecturer from the Optimisation and Logistics Group of the School of Computer Science of The University of Adelaide, SA, Australia, for a research visit from October 24 to November 2. His stay is supported by the Australia-China Young Scientists Exchange Program 2017 (YSEP) [中澳青年科学家交流计划] organized by the China Science and Technology Exchange Center (CSTEC) [中国科学技术交流中心] and the Australian Academy of Technology and Engineering (ATSE).

The members of the Optimisation and Logistics Group in Adelaide research optimization methods that are frequently used to solve hard and complex optimization problems. These include linear programming, branch and bound, genetic algorithms, evolution strategies, genetic programming, ant colony optimization, local search, and others. The areas of interest of Dr. Wagner are heuristic optimization and applications thereof. His work draws on computational complexity analysis and on performance landscape analysis.

Dr. Wagner and the members of our institute will spend most of his visiting time on joint research and on developing future joint projects and collaborations. Additionally, he will visit our colleagues Bin Li at USTC and Xingyi Zhang at Anhui University and give two presentations open for any interested listeners:

  1. Approximation-Guided Many-Objective Optimisation and the Travelling Thief Problem in Anhui University (AHU) [安徽大学] and co-invited by the IEEE CIS Hefei Chapter [slides]
  2. Two Real-World Optimisation Problems Related to Energy at our group [slides (android energy consumption), slides (wave energy)]
