Sandbox Learning: Try without error?

Authors: Christian Müller-Schloer

Published in: Dagstuhl Seminar Proceedings, Volume 9201, Self-Healing and Self-Adaptive Systems (2009)

Abstract
Adaptivity is enabled by learning. Natural systems learn differently from technical systems. In particular, technical systems must not make errors. On the other hand, learning seems to be impossible without occasional errors. We propose a 3-level architecture for learning in adaptive technical systems and show its applicability in the domains of traffic control and communication network control.

The Role of Models in Self-adaptive and Self-healing Systems

Authors: Jens Happe, Heiko Koziolek, Umesh Bellur, Holger Giese, Wilhelm Hasselbring, Robert Laddaga, Margaria Tiziana, Josu Martinez, Christian Müller-Schloer, and Roland Reichle

Published in: Dagstuhl Seminar Proceedings, Volume 9201, Self-Healing and Self-Adaptive Systems (2009)

Abstract
Self-healing and self-adaptive systems dynamically react on changes in the environment. They enable software systems to adjust to new conditions and work optimally even in unstable environments. However, such systems have to cope with an ever increasing complexity and size of software systems. In order to handle such systems, models are an efficient means for analysis, control, and documentation. Furthermore, hierarchically structured models can make self-healing and self-adaptation manageable. In this report, we discuss several questions that address the role of models in self-healing and self-adaptive systems. We outline today's challenges and present different viewpoints on the application and benefit of models.

08141 Executive Summary – Organic Computing - Controlled Self-organization

Authors: Kirstie Bellman, Mike Hinchey, Christian Müller-Schloer, Hartmut Schmeck, and Rolf Würtz

Published in: Dagstuhl Seminar Proceedings, Volume 8141, Organic Computing - Controlled Self-organization (2008)

Abstract
Organic Computing (OC) has become a challenging vision for the design of future information processing systems: As they become increasingly powerful, cheaper and smaller, our environment will be filled with collections of autonomous systems equipped with sensors and actuators to be aware of their environment, to communicate, and to organize themselves in order to perform the actions and servic-es that seem to be required. However, due to increasing complexity we will not be able to explicitly design and manage all intelligent components of a digitally enhanced environment in every detail and anticipate every possible configuration. Therefore, our technical systems will have to act more independently, flexibly, and autonomously, i.e., they will have to exhibit life-like properties. We call such systems "organic". Hence, an "Organic Computing System" is a technical system, which adapts dynamically to the current conditions of its environment. It will be self-organizing, self-configuring, self-healing, self-protecting, self-explaining, and context-aware.

06031 Abstracts Collection – Organic Computing – Controlled Emergence

Authors: Kirstie Bellman, Peter Hofmann, Christian Müller-Schloer, Hartmut Schmeck, and Rolf P. Würtz

Published in: Dagstuhl Seminar Proceedings, Volume 6031, Organic Computing - Controlled Emergence (2006)

Abstract
Organic Computing has emerged recently as a challenging vision for future information processing systems, based on the insight that we will soon be surrounded by large collections of autonomous systems equipped with sensors and actuators to be aware of their environment, to communicate freely, and to organize themselves in order to perform the actions and services required. Organic Computing Systems will adapt dynamically to the current conditions of its environment, they will be self-organizing, self-configuring, self-healing, self-protecting, self-explaining, and context-aware. From 15.01.06 to 20.01.06, the Dagstuhl Seminar 06031 ``Organic Computing – Controlled Emergence'' was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. The seminar was characterized by the very constructive search for common ground between engineering and natural sciences, between informatics on the one hand and biology, neuroscience, and chemistry on the other. The common denominator was the objective to build practically usable self-organizing and emergent systems or their components. An indicator for the practical orientation of the seminar was the large number of OC application systems, envisioned or already under implementation, such as the Internet, robotics, wireless sensor networks, traffic control, computer vision, organic systems on chip, an adaptive and self-organizing room with intelligent sensors or reconfigurable guiding systems for smart office buildings. The application orientation was also apparent by the large number of methods and tools presented during the seminar, which might be used as building blocks for OC systems, such as an evolutionary design methodology, OC architectures, especially several implementations of observer/controller structures, measures and measurement tools for emergence and complexity, assertion-based methods to control self-organization, wrappings, a software methodology to build reflective systems, and components for OC middleware. Organic Computing is clearly oriented towards applications but is augmented at the same time by more theoretical bio-inspired and nature-inspired work, such as chemical computing, theory of complex systems and non-linear dynamics, control mechanisms in insect swarms, homeostatic mechanisms in the brain, a quantitative approach to robustness, abstraction and instantiation as a central metaphor for understanding complex systems. Compared to its beginnings, Organic Computing is coming of age. The OC vision is increasingly padded with meaningful applications and usable tools, but the path towards full OC systems is still complex. There is progress in a more scientific understanding of emergent processes. In the future, we must understand more clearly how to open the configuration space of technical systems for on-line modification. Finally, we must make sure that the human user remains in full control while allowing the systems to optimize.

06031 Executive Summary – Organic Computing – Controlled Emergence

Authors: Kirstie Bellman, Peter Hofmann, Christian Müller-Schloer, Hartmut Schmeck, and Rolf P. Würtz

Published in: Dagstuhl Seminar Proceedings, Volume 6031, Organic Computing - Controlled Emergence (2006)

Abstract
Organic Computing has emerged recently as a challenging vision for future information processing systems, based on the insight that we will soon be surrounded by systems with massive numbers of processing elements, sensors and actuators, many of which will be autonomous. Because of the size of these systems it is infeasible for us to monitor and control them entirely from external observations; instead they will need to help us monitor, control and adapt themselves. To do so, these components will need to be aware of their environment, to communicate freely, and to organize themselves in order to perform the actions and services that are required. The presence of networks of intelligent systems in our environment opens up fascinating application areas but, at the same time, bears the problem of their controllability. Hence, we have to construct these systems which we increasingly depend on as robust, safe, flexible, and trustworthy as possible. In particular, a strong orientation towards human needs as opposed to a pure implementation of the technologically possible seems absolutely central. In order to achieve these goals, our technical systems will have to act more independently, flexibly, and autonomously, i.e., they will have to exhibit lifelike properties. We call those systems ''organic''. Hence, an ''Organic Computing System'' is a technical system which adapts dynamically to the current conditions of its environment. It will be selforganizing, selfconfiguring, selfhealing, selfprotecting, selfexplaining, and context-aware.
