Self-organization

• Self-organization is a process where the
  organization of a system spontaneously increases,
  i.e., without this increase being controlled by
  the environment or an encompassing or otherwise
  external system.

• Two simple principles
• Birth always occurs near to a bug
• Death may occur anywhere

Conclusions on self-organisation

• Self-organizing processes underlie patterns in
  nature, society, and culture
• What is the relation between individual behavior
  and collective behavior?
• Not always obvious, e.g., termite behaviour
• Nature evolves group behaviors that improve
  fitness
• Society evolves group behaviors that improve
  social acceptance
