چکیده انگلیسی
The search process associated with the quantitative theory-experiment comparison in Low Energy Electron Diffraction surface structural analysis can be very time consuming, especially in the case of complex materials with many atoms in the unit cell. Global search algorithms need to be employed to locate the global minimum of the reliability factor in the multi-dimensional structural parameter space. In this study we investigate the use of the Differential Evolution algorithm in Low Energy Electron Diffraction structural analysis. Despite the simplicity of its mechanism the Differential Evolution algorithm presents an impressive performance when applied to ultra-thin films of BaTiO3(001) in a theory-theory comparison. A scaling relation of N(1.47 ± 0.08) was obtained, where N is the total number of parameters to be optimized.
