Abstract
The diffusion-limited aggregation (DLA) model of cluster growth and aggregation has been extended to include both a finite and variable diffusion length for the particle’s random walk. The new model generates a variety of different structures similar in geometry to the DLA model; however, they lack the fractal scaling indices normally expected from the DLA model. It is postulated that the DLA and Eden models of cluster growth are both limiting cases of the finite-diffusion-length model where the diffusion length approaches infinity and zero, respectively.Keywords
