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