Abstract
We study the evolution of interfaces for a generalization of a diffusion-limited aggregation process in two dimensions, where the walkers are launched from any unoccupied site and have a lifetime τ. For τ=1, the model reduces to variant B of the Eden model. However, Eden model B does not respond to noise reduction in the same way as the other forms of the Eden model (A and C). As τ increases, stable cellular patterns emerge that resemble the patterns in directional solidification.Keywords
