The results agree with the results obtained by Family for the case of nearest neighbour diffusion [F. Family, J. Phys. A 19(8), L441, 1986]. However for larger diffusion steps, the growth exponent and the roughness exponent show interesting dependence on diffusion length.5 pages, 11 figures, 4 tablesSoft Condensed MatterStatistical Mechanicstext
