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