FIGURE 5.
Correlation of structure ranking: (a) HP versus HP′; (b) HP versus HPmax; (c) AB versus ABmax; and (d) HP versus AB models. For a given model, encodable structures are ranked by the sizes of their neutral (convergence) sets. For a pair of models being compared here, the ranks of every structure encodable in both models are provided by the two horizontal scales (the rank can be different in the two models), whereas the number of structures sharing a given pair of ranks is indicated by the vertical scale.
