Abstract
An annealing evolutionary algorithm (AEA), which combines aspects of geneti c algorithms and simulated annealing, is proposed to find the global minimu m of a non-linear least square function for spectral fitting. By applicatio n of the algorithm to the fitting of structural parameters from experimenta l extended X-ray absorption fine structure (EXAFS) spectra of two Cu sample s, it was found that reasonable results were obtained. Comparing with genet ic algorithms and EXCURVE88, the AEA method is faster and more accurate in analysis of EXAFS spectra.
