<div>Composition dependence of all studied elastic properties in the zinc-blende (ZB) structure. Each graph presents one property calculated using all the methods. Filled points represent the supercell (SC) alloy simulation while empty points represent the alchemical mixing (AM). Squares: finite difference method, circles: clamped case of DFPT, and triangles: relaxed case of DFPT.</div>
