Spectral Analysis, Evolution Strategies, and Optimization


In this paper we show how evolution strategies (ES) are successfully applied to the problem of fitting line profiles of stellar spectra, which provides a reliable decomposition. Using a stellar spectrum as input, we implemented an evolution strategy to find its components: continuos spectrum and spectral lines. In our experiments we used Gaussian functions to match spectral lines and three different equations to represent the continuos spectrum. We applied this method to simulated and real spectra.
