Response-Diffusion is sort of a sophisticated process; if you wish to read the mathematical logic, you’ll be able to visit the RD master Karl Sims’ website:

Let’s start with a straightforward analogy:

Response-diffusion systems are a solution to describe how things change and move around, especially if you’re talking about chemicals. Imagine you will have a pair of various paints on a bit of paper, and so they begin to mix and create recent colours — that’s just like the “response” part. The paint blots don’t just stay in a single spot; they unfolded and mix — that spreading is just like the “diffusion” part.

So, these systems are only a algorithm that tell us how these processes occur: how the chemicals react with one another to make recent stuff and the way they move around or unfolded.

This will describe a variety of various things in nature, equivalent to how patterns form on animal skins, how pollution spreads within the environment, and plenty of other situations where stuff is reacting and moving at the identical time!
