Response-Diffusion is kind of a sophisticated course of; if you wish to learn the mathematical logic, you may go to the RD grasp Karl Sims’ web site:
Let’s begin with a easy analogy:
Response-diffusion programs are a approach to describe how issues change and transfer round, particularly once you’re speaking about chemical substances. Think about you’ve a few totally different paints on a chunk of paper, and so they begin to combine and create new colours — that’s just like the “response” half. The paint blots don’t simply keep in a single spot; they unfold out and mix — that spreading is just like the “diffusion” half.
So, these programs are only a algorithm that inform us how these processes occur: how the chemical substances react with one another to make new stuff and the way they transfer round or unfold out.
This will describe numerous various things in nature, similar to how patterns type on animal skins, how air pollution spreads within the atmosphere, and plenty of different conditions the place stuff is reacting and shifting on the identical time!
