By recursive methods, numerically exact free energies are calculated for L×L Ising lattices with bonds of randomly chosen sign, with 6<~L<~18. Ground states of these systems are identified, and the response to ordering fields is studied. By performing Monte Carlo simulations for precisely the same systems we are able to unambiguously distinguish nonequilibrium phenomena from equilibrium ...
