Abstract
Short-time dynamic scaling behavior of the 3D +/- J Ising spin glass is stu died by Monte Carlo methods. Starting the replicas with independent initial configurations with a small pseudo-magnetization, the dynamic evolution of the overlap q(t) between two replicas is measured. The initial increase of the overlap q(t) is observed and the corresponding exponent theta' is obta ined. From the scaling relation lambda = d/z - theta', the dynamic exponent z is estimated.
