Factor Analysis based on RoboCup Midfielder Position

Research on midfield position has an important meaning for the result of RoboCup Simulation 2D. This paper divides the whole region into eight parts, then count the cycle's number of the both player 6, 7, 8 midfielders in the game in the eight regional positions. Next, three common factors were extracted, which were named as midfielder factor, restricted factor and border defense factor. Finally calculate three factors' scores and get the comprehensive evaluation scores. It is found that the top few teams get good results in recent RoboCup World Cup. It confirms the reasonableness of the factor analysis method.
