摘要
Much of the 資訊 about the multi-valley structure of disordered spin systems can be convened in a simple tree structure-a barrier tree-the leaves and internal nodes of which represent, respectively, the local minima and the lowest energy saddles connecting those minima. Here we apply several statistics used in the study of 系統發育 trees to barrier trees that result from the energy landscapes of p-spin models. These statistics give 資訊 about the shape of these barrier trees, in particular about balance and symmetry. We then ask if they can be used to classify different types of landscapes, compare them with results obtained from random trees, and investigate the structure of subtrees of the barrier trees. We conclude that at least one of the used statistics is capable of distinguishing different
