Abstract
For cellular automata versions of Glauber and Metropolis kinetic Ising models in one dimension the critical and domain growth dynamical exponents, Zcr and Zdg are shown to coincide if the dynamical scaling assumption holds. Computer simulations presented yield Zdg=Zcr equal to 2 and 1, respectively, for the Glauber and Metropolis models with checkerboard updating. The latter model with its faster relaxation is suggested as an algorithm superior to the usual Monte Carlo ones.
