The two simulation datasets have distinct differences from each other, as summarized in Table . Despite these differences in terms of noise, dataset size, and crystal symmetry, it is interesting to see that the correlation lengths within a VFZ are similar for the two datasets. Both are lower than 4 Technically the correlation does not go to exactly zero until the length scale is infinite. The values listed here are for a correlation of ρ = 0.01. ) and Fe (Kim et al. ) molecular statics simulation datasets. The differences in noise-levels results from whether multiple initial starting configurations were probed in search of a globally minimized configuration as opposed to using a single metastable configuration.
