The adaptive crystal structures in CuAu and NiPt were discussed. The different fcc configurations whose energies are parametrized using a cluster expansion were searched for the discovery of adaptive crystal structures. The compounds are found to contain a composition range of quasicontinuum of stable, ordered, adaptive structures and this adaptivity was explained through anisotropic long-range strain energy.
