Abstract
We present an efficient algorithm fur finding the first excited state of th e random-field Ising model based on the equivalence of its Hamiltonian with the capacity of cuts of a certain network. Some preliminary results: in th e two-dimensional case with a Gaussian distribution of random fields are pr esented. (C) 2001 Academic Press.
