Introduction Implications Exploration Tips An Advanced Model References


1. Locations in a two dimensional grid can be occupied by two differing sorts of entities, one green and the other red.

2. Each location has eight neighbors (edge locations have neighbors on the other side's edge) and each type of entity has a controllable preference to be surrounded by neighbors like (or different from) themselves. The preference is expressed by a wish to have some particular percentage of the eight neighbors of any entity to be like (or different) from the entity itself.

3. At each time step (iteration) of the model, entities check the relevant percentage of their eight neighbors.

4. If the preference is greater than the preference value, the entities remain where they are. If it is less than the preference value, they move randomly to any open location.

5. The model continues running until no one moves on successive iterations.

The basic model will let you:

  • start with either an integrated (random) or a segregated distribution of reds and greens,
  • control the population size (and hence density),
  • control the strength of preference, and
  • select the direction of preference (similar or different).

See what you discover!
