Abstract:The dynamical critical behaviour of the Ising spin glass is investigated at the damage-spreading threshold . The dynamical critical exponent z is observed as at for d = 2 and at for d = 3 . The fractal dimensions of the damage cluster are estimated as for the 2D Ising spin glass and for the 3D system, which satisfy the equation within the error bar.
