考虑到演化算法的鲁棒性和普适性,可用它来研究H-和He的外场特性.H-和He在外场中基态能的计算问题可转化为一个函数优化问题,用MCI方法处理H-和He的定态波函数,用演化算法求体系的基态能,得到了高精度的结果,且在搜索区间及计算速度的方面较其它优化方法而言都得到了极大的改善与提高.
攷慮到縯化算法的魯棒性和普適性,可用它來研究H-和He的外場特性.H-和He在外場中基態能的計算問題可轉化為一箇函數優化問題,用MCI方法處理H-和He的定態波函數,用縯化算法求體繫的基態能,得到瞭高精度的結果,且在搜索區間及計算速度的方麵較其它優化方法而言都得到瞭極大的改善與提高.

Considering the robustness and commonness, it uses theevolutionary algorithm to calculate the characteristic of H- and He in outfield. The calculation for ground-state energy of H- and He can be converted to a problem of function optimization. At first the MCI method is adopted to deal with state wave-functions of H- and He, then the evolutionary algorithm calculates their ground-state energies. Results show that it can obtain much more accurate results, and compared with other algorithms, it's more efficient.
