The talk presents so-called drift analysis as an important technique for the analysis of randomized search heuristics like evolutionary algorithms, simulated annealing etc. It is shown that drift analysis allows very precise statements on the running time of a simple evolutionary algorithm for the optimization of linear functions. As a consequence, a proof of optimality for an often recommended parameter setting in evolutionary algorithms is obtained. Finally, drift analysis is supplemented by sharp-concentration results. It is demonstrated that the extended drift technique can be applied to problems from classical theoretical computer science, more precisely the analysis of probabilistic recurrence relations.
