Research objective. I want to understand stochastic search in continuous, high-dimensional search spaces. When improving known or developing new algorithms, I strongly care about whether and how they are useful in practice. Typical research means are: markov chain analysis, meaningful comparison methodologies, statistical machine learning techniques, and adaptive parameter control, eventually bridging the gap to the practitioner.

^[1]The H-index is the (largest) number, H, of articles that received at least H citations each.
^[2]The g-index is the (largest) number, g, of cited articles that received at least g citations on average. By definition g ≥ H. Note that usually g ≈ √ number of received citations, because g is the largest number such that g ≤ number of cited articles and g² ≤ number of received citations and the latter is usually the determining factor.
^[3]Citation counts include citations to technical reports and white papers. Including these seems to be appropriate for measuring impact, as they are neither particularly easy to track down nor particularly attractive to cite. Excluding citations from such kind of sources has not been done for purely practical reasons.
