Abstract
We consider the mean-held theory of the random field Ising model obtai ned by weighing the many solutions of the mean-field equations with Bo ltzmann-like factors. These solutions are found numerically in three d imensions and we observe critical behaviour arising from the weighted sum. We estimate the exponents.
