Title: The Precursor of Theory for Discrete EAs: What Happened 25 Years Ago? Speaker: Martin Krejca Abstract: Run time analysis of evolutionary algorithms (EAs), that is, proving mathematical guarantees about the run time of EAs, is currently one of the major areas in the theoretical domain of evolutionary computing. By now, the run time of certain EAs on typical benchmark functions is very well understood, ranging from upper and lower bounds on the expected run time over calculating leading constants to even having a thorough understanding of the entire distribution of the run time in specific cases. But was this always the case? In this talk, we take a look at what theoretical analyses of discrete EAs looked like 25 years ago, when this field was still in its infancy. We dive into the PhD thesis of Günter Rudolph, and we discover what aspects were relevant back then, what results could be derived, what tools were used, and how this compares to our current knowledge. Buckle up for some interesting (re)discoveries!
