ACCEPTANCE-PROBABILITY-CONTROLLED SIMULATED ANNEALING - A METHOD FOR MODELING THE OPTICAL-CONSTANTS OF SOLIDS

A simulated annealing procedure with acceptance-probability control instead of the usual temperature control is proposed. The algorithm presented here has proved to be fully insensitive to initial parameters values, free of local-minima trapping problems, and shows superior convergence compared to adaptive-step classical simulated annealing with exponential cooling schedule. Experiments on computer generated synthetic data (with noise), closely resembling the optical constants of a metal, were performed to verify the effectiveness of the algorithm. The algorithm is then applied to parameter estimation of the model of optical constants of aluminum.
