Agent based simulations
Schelling segregation, network contagion, traffic jam formation, self organised criticality and recommender feedback.
Segregation
A runnable Schelling model. A mild individual preference turning into a segregated map.
Diffusion
The same contagion at the same transmission probability over a lattice, a small world and a scale free network.
Jam
A ring road with nothing blocking it. Set the density and the reaction time, tap one brake.
Pile
A sandpile driven one grain at a time, organising itself to the edge of stability.
Recommender
A feed that decides what each agent sees, run again against a neutral one on the same population.
