Christian Brandlhuber (21 strategies GmbH): Battlefield superiority by enhanced tactics. AI for tactical decision sequences and emergence

Artificial intelligence is already playing an increasingly important role in the timely evaluation of sensor data and is thus making a significant contribution to improving situational awareness. Future systems, however, will go far beyond the ability of pure evaluation and will be able to independently develop tactical behaviour in order to always be one step ahead of the opponent through the intelligent use of their own resources. The lecture presents the possibilities of tactical AI systems that develop emergent behaviour (also called context-aware/consequence-sensitive 3rd wave AI by DARPA) in the areas of Markov decision processes and multi-agent learning based on current results from the dtec.bw project Ghostplay.

Alexander Popp (UniBW M): Scalable computational kernels and linear solvers for FEM-based computational contact mechanics

Targeting simulations on parallel hardware architectures, this seminar talk presents scalable computational kernels and linear solvers for mortar finite element methods in computational contact mechanics. Mortar methods enable a variationally consistent imposition of coupling conditions at high accuracy but come with considerable numerical effort and cost. We identify bottlenecks in parallel data layout and domain decomposition that hinder an efficient evaluation and solution and propose a set of computational strategies to restore optimal parallel communication and scalability.
