Basing the effective nucleon-nucleon force in nuclei on the experimental global parameters of nuclei over the mass, range of {sup 4}He to nuclear matter has been under study for many years. In this work, we emphasize the global constraints of binding energy, size, and the Hartree-Fock (saturation) condition for {sup 4}He, {sup 16}O, and {sup 40}Ca. For symmetric nuclear matter, we also include the effective mass and the incompressibility. We are parameterizing the effective nucleon-nucleon interaction using the form of the Extend-Skyrme force which includes a finite-range density dependence. For {sup 4}He, we have found that we must go beyond the mean-field approximation. This will be discussed along with the results of large-basis shell model calculations using the Extended-Skyrme force.
