Fig. 1: Overview of HEA optimization.
a Schematic phase diagrams of ternary and quaternary alloy systems. The development of traditional alloys is mainly in the corner regions (yellow regions), while the HEA expands toward the center space of the phase diagram (high-entropy (blue) regions); b Binary embedding for lattice configurations. A 2D M × N binary matrix xM×N is used to represent the cell with M types of elements and N atomic sites. For example, xij = 1 means the i-th element will occupy the j-th site.
