Abstract
A method for computing an exact solution for an electronic state of a substance by performing a first principle calculation using a computer, the method is characterized in that evaluating a deviation of an approximate value obtained by local density approximation or generalized gradient approximation from the exact solution of the electronic state to be obtained using an energy functional determined by an electronic density, a space derivative for the electronic density and fluctuations of physical quantities; and computing the exact solution by solving an optimization problem being defined by the energy functional.
