A variational Monte-Carlo method, which is a combination of the variationaltheory and the Monte-Cargo technique is proposed to study the Hubbard model withthe Gutzwiller's wave function. An application is made to one-, two-, and threedimensional models having sites up to 216 (6 X 6 X 6) and arbitrary values of U/ t(on-site repulsion U and hopping integral 75. Contrary to resorting to the Gutzwillerapproximation, it provides a virtually exact way to carry out the Gutzwiller-typevariational theory and opens up a possibility of further development.
