Information Maximizing Agents in a Structured Environment
Abstract This work analyzes representations of the world attained through an infomax principle by agents acting in a simple environment. The representations obtained by different agents differ to some extent from each other. This causes ambiguities in the way the environment is represented. An information-theoretic formalism was developed, able to extract a "common conceptualization" of the world for a group of agents. It turns out that the common conceptualization intuitively seems to capture much higher regularities or symmetries of the environment than the individual conceptualizations.
Abstract Notions for identification of these "weak" symmetries in the environment were formalized, with respect to "extrinsic" operations on the environment as well as with respect to "intrinsic" operations, i.e. the reconfiguration of the agent's embodiment. In particular, using the latter formalism, an agent can be re-written to conform to the highly symmetric common conceptualization to a much higher degree than an unrefined agent; and that without having to re-optimize the agent from scratch. In other words, we can "re-educate" an agent to conform to the de-individualized common language of the agent group with comparatively little effort.

Information Theoretical Models for Hierarchical Structured Agents and their Computation
Abstract This work uses information theoretic methods to describe and analyze agents acting in an environment. Particularly the possibility of reducing complexity of computation inside of such agents by structuring them in a hierarchical manner was investigated. Therefore, a new formalism of describing such agents and their interaction with the world was introduced, the "looped causal Bayesian networks".
Abstract Additionally, algorithms to compute hierarchical structured agents resp. the according looped causal Bayesian networks are presented. They are implemented in a generic and efficient way to enable various kind of experiments with little additional implementation effort.

Analyse von Räuber / Beute Netzen
Numerical experiments about Structure of pray predator systems. This work was done during a 3 month my first university semester at the group of Barbara Drossel.
Planung und Simulation eines Selbstorganisierenden Funknetzwerkes
In unseren Vorrausgehenden Projekten hatten wir immer wieder Probleme mit zu geringen Reichweiten von verwendeten Funkmodulen. Um hier abhilfs zu schaffen versuchten wir uns damals bereits mit dem was heute gemeinhin unter AdHoc- / Mash- oder Sensor Netzwerke gehandelt wird.

dynamisches Fahrgastinformationssystem
In diesem Projekt ging es um die Bereitstellung von Live-Fahrplaninformationen für Nutzer von Omnibussen im ÖPNV. Das Prokekt war damals seiner zeit ein paar Jahre vorraus. Kaum zu glauben das man solche Systeme nun in jeder Stadt findet.
