Complex Adaptive Systems

J. Stephen Lansing
2003 Annual Review of Anthropology  
The study of complex adaptive systems, a subset of nonlinear dynamical systems, has recently become a major focus of interdisciplinary research in the social and natural sciences.  ...  The initial phase of research on nonlinear systems focused on deterministic chaos, but more recent studies have investigated the properties of self-organizing systems or anti-chaos.  ...  The Santa Fe Institute, the Center for Advanced Study in the Behavioral Sciences at Stanford, and the University of Arizona provided opportunities for reflection and discussions with colleagues.  ...

Towards self-adaptive MPSoC systems with adaptivity throttling

Wei Quan, Andy D. Pimentel
2015 2015 International Conference on Embedded Computer Systems: Architectures, Modeling, and Simulation (SAMOS)  
To cope with such dynamic application behavior, these systems could dynamically adapt the mapping of application tasks onto the underlying system resources to improve the system's performance.  ...  behavior to predict the actual benefit of a system reconfiguration to allow for explicitly deciding (at runtime) whether or not to reconfigure.  ...  The decision of whether or not to reconfigure is made based on the scenario execution pattern. By using the proposed approach, the system can adapt its behavior according to e.g. user behavior.  ...

Adaptation Patterns for Interactive Systems [chapter]

Matthias Bezold, Wolfgang Minker
2011 Adaptive Multimodal Interactive Systems  
Collections of such patterns also exist for graphical interfaces and adaptive hypertext. However, a collection of patterns for adaptive interactive systems does not exist.  ...  Other approaches even formalize the semantics of the adaptation patterns.  ...  Acknowledgements The author is indebted to Paul Adamczyk, the shepherd of this paper for Euro-PLoP 2009, for his time, comments, and observations, which allowed the paper to evolve during the shepherding  ...

Studying Complex Adaptive Systems

John H. Holland
2006 Journal of Systems Science and Complexity  
Complex adaptive systems (cas) -systems that involve many components that adapt or learn as they interact -are at the heart of important contemporary problems.  ...  The study of cas poses unique challenges: Some of our most powerful mathematical tools, particularly methods involving fixed points, attractors, and the like, are of limited help in understanding the development  ...  After hundreds of years of study we still find new patterns and strategies for playing these games. For a cas the rules that define the agents' behavior are the equivalent of the rules of the game.  ...

Exploring Engineered Complex Adaptive Systems of Systems

Bonnie Johnson, Alejandro Hernandez
2016 Procedia Computer Science  
The rise of automation in many systems; and technology ubiquity in general, present some complex operational environments that require highly collaborative Complex Adaptive Systems of Systems (CASoS) solutions  ...  This effort builds on a developing body of knowledge in complex systems and focuses on understanding characteristics and measures of CASoS with an ultimate goal on developing engineered CASoS.  ...  It can also be measured by studying how much the behavior adapted in terms of changes to the CASoS architecture, changes to the states of constituent systems, and changes in the SoS state.  ...

Patterns for self-adaptive systems: agent-based simulations

Mariachiara Puviani, Giacomo Cabri, Franco Zambonelli
2015 EAI Endorsed Transactions on Self-Adaptive Systems  
Self-adaptive systems are distributed computing systems that can adapt their behavior and structure to different kinds of conditions.  ...  Starting from that theoretical work, we have simulated the described self-adaptation patterns, in order to better understand the concrete and real features of each pattern.  ...  Acknowledgements Work supported by the ASCENS project EU FP7-FET, Contract No. 257414 and by the "Linea strategica SMART ICT FOR SMART SOCIAL WORLDS" of the Università di Modena e Reggio Emilia.  ...

Adaptive information search

Jessie Chin, Wai-Tat Fu, Thomas Kannampallil
2009 Proceedings of the 27th international conference on Human factors in computing systems - CHI 09  
We conducted a study involving younger and older adults to compare their web search behavior and performance in illdefined and well-defined information tasks using a health information website.  ...  Older adults compensated for their lower cognitive abilities by adopting a top-down knowledge-driven strategy to achieve the same level of performance in the ill-defined tasks.  ...  Studies have evaluated web search behavior of older adults because they are most likely the consumers of health information.  ...
