【 摘 要 】

We use first-order renormalized forward scattering coupled to a simulated annealing optimization algorithm to get the unknown structural parameters of a surface over a wide range of different possibilities. The method is very fast and provides in an automated manner a quasi-global solution ready to be further refined using other techniques.
