The Algorithm Engineering group hosts three scientific guests in March and April. At the beginning of the month, we welcomed Amirhossein Rajabi who is currently a PhD student at the DTU Copenhagen working on the theory of evolutionary algorithms. His visit is supported by the Independent Research Fund Denmark. Since mid-March, Thomas Sauerwald (U Cambridge) is our second guest. He is a Mercator Fellow with the DFG project on Algorithms, Dynamics, and Information Flow in Networks. The third visitor will be Frank Neumann (U Adelaide) from the beginning of April, supported by a Humboldt Research Fellowship.
