These strategies are realized via different manners, such as shape deformations or by the use of appendages. In an effort to understand the locomotion of these microswimmers under low Reynolds number conditions, models have been proposed, which are based on fixed swimming strategies. However, models of such organisms that adapt their swimming strategies to the ever changing surroundings have rarely been investigated, so far. I will report about a project where a simple microswimmer model is trained to swim and to uptake nutrients by combining the equations-of-motion with modern tools of machine learning. Using genetic algorithms optimized neural networks are developed which control the shape deformations of the microswimmers and allow them to navigate in static and time-dependent chemical environ-ments. By introducing noisy signal transmission in the neural networks the well-known biased run-and-tumble motion emerges, as it is known for many swimming microorganisms. Extensions of the simple model in use to more realistic microswimmers are discussed. Microswimmers learning chemotaxis
