摘要：
We use a constrained Monte Carlo technique to analyse ultrametric features of a four-dimensional Edwards-Anderson spin glass with quenched couplings J = +/-1. We find that in the large volume limit an ultrametric structure emerges quite clearly in the overlap of typical equilibrium configurations.
