Reinforcement Learning in the Wind

Deep reinforcement learning is an AI technique for choosing how to act in different situations repeatedly occurring over time. It has shown tremendous success in playing games, such as ATARI video games, chess, Go, and StarCraft, going as far as beating professional human players. While games present certain interesting scientific …

What have satellite scheduling, the selected traveling salesperson (orienteering) problem, and make-to-order manufacturing in common?

First, these problems can all be modeled as a single-machine scheduling problem with release times, deadlines, time/sequence dependent setup times, and rejection, which is strongly NP-hard. Second, most instances are solved either best or fastest with one of our new algorithms! Some instances have been solved by us to optimality …

My aim is to support and further increase the exchange of knowledge and experience between Dutch Railways and Delft University of Technology. I aim …

Solving Road Congestion Problems with Algorithms?

State-of-the-art in-car navigation systems contribute to preventing road congestion, because avoiding traffic jams helps dissolving it. Currently, the more advanced systems already are using both historic travel times as well as recently observed travel times to estimate future travel times for road segments, and base their route navigation advice upon …
