Grading

  • one test will be given after the foundation as a test

for you to check what you have learned. The test score will add an optional 20% to your final grade.

  • At the end of your module a klausur will be given
  • n the theoretic foundation and the phenomena.
  • your seminar presentation will count towards your

final grade as well.

what are complex systems?

slide-25
SLIDE 25

Complex Systems

  • simple rules generate complex, emergent

behavior

slide-26
SLIDE 26

Complex Behavior

  • unpredictable
  • structured
  • emergent
  • self-organized

  • dynamic
  • self-similar
  • critical
  • pattern forming

example: the game of life

  • cells can be dead or alive
  • Every living cell considers 8

nearest neighbors and counts living neighbors K

  • when K<2 the cell dies
  • when K=2 or K=3 the cell

lives

  • when K>3 the cell dies
  • a dead cell is born when 3

neighbors are alive
