Workshop 'Combinatorics, Algorithms, and Geometry'

Location: Hofgärtnerhaus Dresden
Dates: 29.08.-02.09.2022

The goal of the workshop is to bring together researchers at the interface of combinatorics, algorithms and geometry, and to collaborate on interesting research problems. This is the second edition of the workshop, after the successful first edition in 2021 that took place in Wittenberg, Germany.
