【Abstract】 It’s very difficult to calculate the accurate ground state energies of systems like helium in the strong magnetic field. In this paper we firstly adopt MCI method to spread the state wave function with Slater bases, then secondly use evolutionary algorithm to optimize its variation parameters, last resolve the definite state Schrdinger equation to obtain the better results of this system. The results show that because of applying the evolutionary algorithm to obtain the best parameters, we can correctly confirm a group of bases. It has an important effect in veracity and reliability of calculating the gound state energy of systems like helium.更多还原
