We explore the possibility of modifying the multiplicity of the basic cluster in the entropy functional used in the cluster variation method so that truncation errors owing to finite size of the basic cluster may be corrected. The numerical value of this multiplicity is found by requiring the modified CVM entropy functional (M-CVM) in the tetrahedron approximation for the body-centered cubic structure to yield the exact critical temperatures for ordering and phase separation. We demonstrate…
