Avoiding unstable regions in the design space of EUV mirror systems comprising high-order aspheric surfaces

When Extreme Ultraviolet mirror systems having several high-order aspheric surfaces are optimized, the configurations often enter into highly unstable regions of the parameter space. Small changes of system parameters lead then to large changes in ray paths, and therefore optimization algorithms crash because certain sssumptions upon which they...

Models, Solutions and Relaxations of the Asymmetrical Capacitated Vehicle Routing Problem

In this thesis, we take a look at the Asymmetrical Capacitated Vehicle Routing Problem (ACVRP). We will take a look at different possible formulations for the problem and choose one based on the ease of implementation, the computation speed of solving it, and the available relaxations. The problem, and its relaxations, will be modeled and solved...
