摘　　要：将求磁场中原子的基态能问题转化成了一个函数优化问题，同时考虑到演化算法在非线性函数优化方面的优越性，将它们结合起来进行了有益的尝试．结果表明演化算法与其他的优化算法相比，能更加有效地用于基态能量的计算，并能在物理学的其他领域得到成功的应用．It's very difficult to calculate the accurate ground-state energies of the double-electron systems in a uniform magnetic field. 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.
