Abstract
Multi-objective optimization of ski jumping flight was carried out, and then the trade-offs between the objective functions and the control variables could be visualized using Self-Organizing Maps. It was assumed that there are four objective functions and eighteen control variables in this case. Three of the four objective functions are concerned with the style point, and the other is the flight distance. It was found that that the longer the flight distance the smaller the style point. The forward leaning angle and the angular velocity in the nose-down direction should be almost 0 and 10 degrees at 0.3 seconds.
