A* Algorithm Analysis and Optimization: In Network Game Design

In this paper, we first describe the basic principle and the method of the A* algorithm. And we analyze the reason that the A* algorithm influences speed when it is searching for the optimum route in network game map. Then we give the optimization scheme from the aspects of node data structure to the maintenance of the open queue. At the same time, the optimization scheme is evaluated and tested by a number of different game maps. Finally, through experiment, we can have the conclusion that the improvable A* algorithm is practical and feasible. And the A* algorithm can increase the speed of playing the game and can been implemented in the specific network game.
