Abstract
Monte Carlo studies for a biased diffusion are made on simple-cubic random lattices containing and sites with time steps up to . Above the percolation threshold, we observe diffusion for short times, and drift for long times, when the bias is below a characteristic value. For larger bias, a very slow relaxation, presumably to the asymptotic nonclassical behavior, is observed.
