Comparison of Aerosol Size-Distributions Using Linear-Regression, Genetic Algorithm, and Annealing Genetic Algorithm

Abstract Stability and accuracy of retrieving the aerosol size-distribution by using the linear-regression (LR), genetic algorithm (GA), and annealing genetic algorithm (AGA) were studied in detail. It was found that by using the AGA, retrieval results are quite stable and accurate; using the GA, stability and accuracy of the retrieval results decreased mildly but were still acceptable; and using the LR, retrieval results were too unstable to be acceptable. This conclusion is verified by both of the numeric simulation and the experiment.
