井字棋人机对弈，实现基本的人机交互界面，采用图形化界面显示棋盘和棋子。电脑能根据人下的棋，判断下一步较优的走法。井字棋实现人机对弈，为了实现智能化，要为每一步棋估值，采用极大极小值算法，负极大值算法，alphabeta等算法得出较优的下一步棋。平时一个人也可以下棋自娱自乐了。

井字棋人机对弈为我一个人一组完成。

-Tic-tac-toe man-machine chess, to achieve the basic man-machine interface, graphical interface display board and pieces. According to computer chess people under the next judge on better moves. Tic-tac-toe realize man-machine chess, in order to achieve intelligent, To every move valuations using Minimax algorithm, negative maximum value algorithm, alphabeta on better algorithms derived next move. Usually a person can also play chess entertain. Tic-tac-toe for me a man-machine chess groups of completion.
