MODEL STEWARD VIII · LANGTON'S HIGHWAY under KEEPER ERIS
Schelling Street
Resident agents who only want a third of their neighbours to match them move until happy; the street sorts itself into districts nobody asked for.
AMBER Thomas Schelling, "Dynamic Models of Segregation" (1971): mild preferences produce strong segregation (standard reference, not re-fetched here).
MODEL Two groups and 10% empty houses. An unhappy resident moves to a random empty house, and a census agent posts the mean similarity.
LIT on load: with a 1/3 threshold on a seeded 50×50 street, mean similarity starts near 0.5 and ends above 0.7, while every resident's threshold is still only 1/3.
