GI-Theorietag 2023

84th Workshop on Algorithms and Complexity ("GI Theorietag")

Date: 6 March 2023, directly followed by STACS 2023

Location: Hamburg University of Technology, Schwarzenberg campus (see here for directions), lecture hall A0.13 in the main building A which has barrier-free entrance access.

Invited Plenary Speaker: Prof. Sebastian Siebertz, Bremen University

Participation is free of charge.

The workshop is aimed at all those interested in research in the field of theoretical computer science. The focus is mainly on complexity, algorithms and data structures, as well as parallel and distributed algorithms. We welcome presentations by junior researchers (PhD students) and senior researchers on recent topics in algorithms and complexity. There are no formal proceedings, so both published and unpublished work can be presented, without interfering with any past or future publication. A declared goal of the workshop is to enable contact between young and senior scientists.

The 84th Theorietag of Gesellschaft für Informatik will take place at Hamburg University of Technology (TUHH). This workshop is organized by the Institute for Algorithms and Complexity and the Research Group for Theoretical Computer Science at TUHH.
