Description	Period analysis of eclipsing binaries can be performed effectively when using fine-tuned phenomenological models. The combination of regression analysis and genetic algorithms is a powerful tool for such astrophysical tasks as light curve analysis, mid-eclipse time determination and O - C diagram investigation - even apsidal motion and light time effect can be resolved.
