摘要：

Two-dimensional Ising spin glass with Gaussian couplings is studied through different real-space renormalization-group procedures. The stiffness exponent y, associated with the evolution of the coupling distribution at zero temperature, is computed. Our results are discussed and compared with other estimates available.
