Phys. Rev. A 39, 1365–1368 (1989)Quantitative growth law of diffusion-limited aggregates and their small-mass behaviorReceived 29 September 1988; published in the issue dated February 1989 The behavior of aggregates grown using random walkers is shown to be quantified by a unique equation for different variations of the original diffusion-limited aggregation model. Only four parameters (including the fractal dimension) are needed for describing this behavior, each of them having a clear physical significance. Two parameters correspond to two different length scales: the branch width, which is associated with asymptotic behavior, and the seed size, which determines the small-mass behavior. © 1989 The American Physical Society URL:
