A simple general method is presented for solving mean-field spin-glass models where the bond-randomness is expressible in terms of an underlying site-randomness. The method is based on the observation that the Hamiltonian of these models is a quadratic form of sublattice magnetizations and that the free energy can be evaluated in terms of eigenvalues and eigenvectors without using replicas. Both separable and non-separable models can be solved. While for separable models the number of order-parameters necessary to describe a system is independent of the probability distribution for the site-variables this proves not to be the case for the non-separable models, where this number increases, as continuous distributions are approached.Nous prés...
