Abstract
The article [Phys. Rev. E {\bf 73}, 031111 (2006)] by Horowitz and Albano reports on simulations of competitive surface-growth models RD+X that combine random deposition (RD) with another deposition X that occurs with probability . The claim is made that at saturation the surface width obeys a power-law scaling , where is only either or , which is illustrated by the models where X is ballistic deposition and where X is RD with surface relaxation. Another claim is that in the limit , for any lattice size , the time evolution of generally obeys the scaling , where is Family-Vicsek universal scaling function. We show that these claims are incorrect.
