learning to pass and receive the ball.
This type of skill is qualitatively different from the individual skills in that the behaviors of multiple agents must be coordinated. A "good" pass is only good if it is appropriate for the receivers receiving action, and vice versa. For example, if the passer passes the ball to the receiver's left, then the receiver must at the same time move to the left in order to successfully complete a pass. As above, such coordination can carry over from game to game, thus allowing off-line learning techniques to be used [].
