In addition, each player may participate in a maximum of three individual and collective projects are not restricted. To enable the player to normal competition, the need to schedule to make reasonable arrangement. Please constructed on the model and data structure, reasonable arrangement designed algorithms and program schedule, so that each player will normally participate in the competition and called for playing time as short as possible
