In this paper, according to the feature of this problem, we transform this physical problem to a function optimization problem. Also considering the feature of evolutionary algorithm, we apply it to calculate the ground-state energy of the double-electron systems. The results show that compared with other algorithms such as simplex method, evolutionary algorithm is more efficient in calculating atomic energies, and can be used in the other fields of the physics. 演化算法 二电子体系 基态能 修正的组态相互作用方法（MCI） 函数优化 evolutionary algorithm double-electron ground-state energy modified configuration interaction method（MCI） function optimization 10.14188/j.1671-8836.2000.01.007 O562 国家自然科学基金!（69703011） 2000-01-01 2021-04-01 1
