Fig. 1: Optimal transport cell generation.
From: Soliquidy: a descriptor for atomic geometrical confusion

a The grey filling of the cell represents the translationally disordered state, while the black dots represent the center of atoms fixed in the solid state (randomly placed to emphasize different cell forms); (b) each atom is assigned a cell using Voronoi tessellation; and (c) final generated Voronoi cells with optimized growth rate resulting in equal portions of the cell area, the original cells are outlined with dashed gray lines.
