Non-traditional method of parameter search for non-linear models

The construction method of non-linear models, based on the accidental parameter search is described. The transformation parameters obtained by new algorithm make it possible to decrease F-ratio of the model by several times as compared with the traditional methods. The usage of this algorithm allowed to describe adequately some processes, for which such a description couldn't be obtained through the succesive approximation method. The application of the method is illustrated by modelling of hafnium and zirconium extraction process with capryl alcohols, as well as by rhenium-tungsten-nickel alloy electrodeposition
