WebFour parameters are relevant to our reaction-diffusion system: the feed rate (f) of A particles, the kill rate (k) of B particles, the predator-prey reaction rate (r), and the diffusion rate (i.e., speed) of B particles. We do not need to set the diffusion rate of A particles, since we know that their diffusion is twice that of B particles.

WebJan 28, 2024 · For reaction-diffusion, this means any case with Michaelis-Mentons or Hill functions. So assume f is “trivial enough” that you still want to optimize the stencil part all of the way ( f (x) = -x^2 for example). There are two ways to approach this: Stencil compilers are fast, so calculate y=A*x then do y .+ f.
