Visual analysis of a set of function values

The goal of investigation was to seek new features far the analysis of extremal problems. A method of visual analysis of a set of objective function values is proposed. It allows us to find a direction where the variation of function is maximal. The method ensures a high quality of analysis when the number of used values of the objective function is small, and a possibility of identifying the specific character of the objective function. The results of analysis are used in the search for a new coordinate system of the extremal problem and in a graphical representation of the observed data. The analysis would allow us to find a better optimization strategy
