We strongly condemn Russia's aggressive attack on Ukraine for which there is no rational justification. We stand firmly with the Ukrainian people.

In a project presented at the "Long Night of Sciences" (LNdW) in June 2015, we illustrate the concept of finding shortest ways on (unweighted) graphs and its relations to various applications. The project involves self-built LEGO Mindstorms robots which can freely explore our two-dimensional mazes, aiming at finding a hidden target and the shortest possible way to get to it. The pro's and con's of different maze solving algorithms (such as "always left", "depth first", and simple "Monte Carlo") become intuitively apparent.
