Java实现五子棋AI算法
Java实现五子棋AI算法
五子棋AI算法 也算是一个典型的游戏AI算法，一些棋类的AI算法都可以参考实现，下面是java实现代码
棋盘抽象接口
import java.util.List;
public interface IChessboard {
//取得棋盘最大横坐标
public int getMaxX();
//最大纵坐标
public int getMaxY();
//取得当前所有空白点，这些点才可以下棋
public List
}
棋子类实现
//棋子类
public class Point {
// 这了性能，设成公有
public int x;
public int y;
public int getX() {
return x;
}
public Point setX(int x) {
this.x = x;
return this;
}
public int getY() {
return y;
}
public Point setY(int y) {
this.y = y;
return this;
}
public Point(int x, int y) {
this.x = x;
this.y = y;
}
@Override
public int hashCode() {
return x + y;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
Point other = (Point) obj;
if (x != other.x)
return false;
if (y != other.y)
return false;
return true;
}
}
玩家抽象接口
import java.util.List;
public interface IPlayer {
//下一步棋子，传入对手已经下的棋子集合
public void run(List
public boolean hasWin();
public void setChessboard(IChessboard chessboard);
public List
}
