✦ Synopsis

We present an efficient algorithm for finding the first excited state of the randomfield 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.

We present an efficient algorithm that, combined with a max-flow, min-cut minimization algorithm, makes it possible to find the ground states of the Gaussian Random Field Ising model when the external applied field B is continuously varied from -∞ to +∞. The algorithm exactly finds all the possible
