Abstract:
The authors adapt the multiple hit method of noise reduction introduced earlier for diffusion-limited growth to Eden models A and C on the square lattice. The dynamic scaling is improved considerably: they obtain 0.33+or-0.015 (model A) for the dynamic exponent beta of surface roughening with relatively small computing effort. Results for model C support universal
