From September 21-25, 2020 leading experts (see the list below) will speak about important concepts and recent developments in the field of computational methods. Our recent Summer School will be complemented by computer tutorials to provide insights into the implementation and performance of various algorithms. Have a look at the schedule. The summer school will be an online event due to the Covid-19 situation. We organize the event on-site but with a proper streaming of all the lectures and exercises. If the situation relaxes in September and the regulations will permit we do it as a hybrid event.
