Design Patterns for SOS?

• The idea of reuse existing, proven solutions seems to be interesting...
• The usage of design patterns depends on the nature of the desired system
• Focus on mechanisms that cause systems to be SOS
• Use a pattern at design time, so that a SOS runtime behaviour shows up
• Kategorize types of SOS and assign possible design patterns, which are useful for which type
• Checklist seems currently to be more appropriate, we know what is necessary to get SOS
• Checklist for basic properties of SOS: Adaptivity, Emergence, Autonomy, Decentralisation, Cognition, Feedback, Multiple intercations
• Runtime effects to show up: spatial temporal structures, muliple stability, parameter bifurcation

Desing Patterns

• Patterns of coordination
  • Stigmergy
  • Combine positive/negative Feedback w. Balance
• Control Theory -> Feedback
• Coupling between local interactions and global behaviour

Related Work on Design Patterns

In software engineering: a design pattern is a general reusable solution to a commonly occurring problem in software design. A design pattern is not a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations [1]
