Usually modelled through chemotaxis
There are a few parameters we can control in the slimemold model. The main ones are:
These all result in different outcomes.
For example, if you increase the density, you end up with world filled with pheromones very quickly. But the model eventually starts to converge to aggregation.
Aggregation is however very sensitive to the density of pheromone. At half strength, aggregation still happens, but the clusters are much smaller.
Any lower and aggregation stops.
