Abstract
It is demonstrated that the finite-time scaling approach, derived from the forced oscillator method, to determine the exponent of the ac con ductivity sigma(omega) proportional to omega(delta) near the metal-ins ulator transition point is a very powerful me-hod for evaluating the p recise value of the exponent delta with high speed and accuracy.
