Considering the robustness and commonness, it uses the evolutionary 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. [
