Краткий обзор статьи: We present a Monte Carlo study of the d=3 gauge glass and the XY–spin glass models in the vortex representation. We investigate the critical behavior of these models by a scaling analysis of the linear resistivity and current– voltage characteristics, both in the limits of zero and strong screening of the vortex-interactions. Without screening, both models show a glass transition at a finite temperature and, within the numerical accuracy, exhibit the same critical exponents: z approx 3.1 and nu=1.3 +- 0.3. With strong screening, the finite temperature glass transition is destroyed in both cases and the same exponent nu=1.05 +- 0.1 is found at the resulting zero temperature transition.
