380-384.
Using symbolic capabilities of MATHEMATICA software,a package(VCE 1.0) is developed to use for variational cumulant expansion study in lattice models with neiboring interaction.Enumerating high order connected diagrams and analytical expansions of free energy and so on can be obtained by this package.This package can also be used to study some models of lattice gauge theory and statistical physics.
