摘要
In this article we investigate a cellular automaton simulation of the non-linear diffusion equation. The diffusion coefficient characterizing the equation is used to locally bias the random walks of particles on a square lattice. Emphasis is placed on respecting the massively parallel nature of the automaton model, while also correctly simulating the macroscopic behavior described by the equation. The result, a highly parallel algorithm, presents an interesting possibility for parallel and dedicated machines.
