Micro Hypothesis

1

• Micro Hypothesis
• - Individuals act randomly
• according to probabilistic micro-laws
• - stable steady state macro (collective)
• behavior emerges.

2
Micro-law Postulates

• individual determines
• Number of flakes
• Which flakes to stay in
• Which flakes to join
• parameters govern how

3
Number of Flakes
Node has an energy
Energy used in each flake
Energy can be surplus - join new flake
Energy can be deficit - leave a flake
Energy is updated
4
Energy Update
JOIN
NO CHANGE
LEAVE
5
Staying in or Joining a Flake

• Staying

Desired Outcome

• -Individuals act randomly
