Beschreibung:
Motile active matter systems are composed of a collection of agents, each of which extracts energy from the surrounding environment in order to convert it into self-driven motion. At the microscopic scale, however, directed motion is hindered by the presence of stochastic fluctuations. Living microorganisms, therefore, had to develop simple yet effective propulsion and steering mechanisms in order to survive. We may turn the question of how these processes work in nature around and ask how they should work in order to perform a task in the theoretically optimal way, an issue that falls unde...
