Abstract: The genetic algorithms(GAs) is applied for the low electron energy diffraction(LEED) calculation. A computer program GAs-LEED has been developed to perform the automatic search of surface structure. It is found that the GAs-LEED analysis of Pt(111)-p(2×2)0 shows a global minimum in the parameter space.

Key words: genetic algorithms(GAs), low electron energy diffraction(LEED), surface structure automatic search
