WebPeak Fitting uses the Levenberg-Marquardt (LMFit) algorithm, which is widely used for non-linear curve-fitting problems. LMFit is well documented in the literature. From starting estimates it varies peak parameters, calculates a spectrum from those peaks, and evaluates the goodness of fit to the sample spectrum.
