Various Uses of Potential Map in a Soccer Game
J.J. Wagner, Marián Lekavý · 2008
In many environments, it is possible to store the knowledge about the environment in a potential field, instead of expressing the knowledge explicitly. Potential field is also a powerful tool for agent and multi-agent control and coordination. Majority of approaches based on potential fields focus on the navigation and collision avoidance problem or on work or agent distribution. There also exist some approaches to situation evaluation and strategic decision making. This paper presents several approaches to coordination and teamwork in a simulated soccer game, based on the combination of a potential field map and analytical approach. The potential field is used to create a 'fitness map' of the field, while analytical approaches use this map to find the best target and chance of success for individual player skills. Combination of potential field with analytical approaches helps overcoming local extremes, which are a major problem for pure potential field approaches. The presented approaches based on the potential field include team passes (safe passes + predictive pass interception), shooting, dribbling, oside trap avoidance and adapting formation to opponent.
