摘要：

The density of never changed opinions during the Sznajd consensus-finding process decays with time t as 1/t(theta). We find theta similar or equal to 3/8 for a chain, compatible with the exact Ising result of Derrida et al. In higher dimensions, however, the exponent differs from the Ising theta. With simultaneous updating of sublattices instead of the usual random sequential updating, the number of persistent opinions decays roughly exponentially. Some of the simulations used multi-spin coding.
