Voir la notice de l'article

The article describes a new unusual approach to assessing the quality of numerical optimization methods and solving systems of equations, based on the analysis of areas of attraction of singular points - extrema and roots. Along the way, objects of modern fine art (design) with mathematical and even mystical meanings are generated. A specific system of equations is considered as a person from whom a portrait is being painted. The applied methods of numerical solution of the system of equations are the individual styles of a particular artist.
