【问题描述】：
所以这是一项大学作业，除了 AI 不知道如何“取胜”，而且一开始的动作不像我希望的那样随意，一切都已完成走到顶角，一路向下。这项任务只需要人工智能的两条规则，即它可以“赢得胜利”或“阻止胜利”。
当棋盘被填满时，游戏似乎并没有结束。它要求我选择我的行动。
我希望有人能对我如何改进它提出建议，或者指出我哪里出了问题。
任何帮助将不胜感激。
这里有戏
import java.util.Scanner;
public class play {
public static void main(String[] args) {
System.out.println("Welcome to Tickle Tackle Toe!!! :D");
System.out.println();
//creat markers
String marker1 = "x";
String marker2 = "o";
boolean playAgain = true;
Scanner s = new Scanner(System.in);
//create player objects
Human human = new Human();
Computer computer = new Computer();
while(playAgain){
//run board setup
set Setup = new set();
Setup.createBoard();
Setup.printBoard();
System.out.println("please choose your marker");
System.out.println("type 1 for 'x' or 2 for 'o'");
//set markers
if(s.nextInt() == 1){
// create player objects
human.setMarker("x");
computer.setMarker("o");
}
else
{
human.setMarker("o");
computer.setMarker("x");
}
// determine who goes first
int first = (int) (Math.random() * 2);
boolean won = false;
int turns = 0;
if(first == 0){
System.out.println("You go first!");
System.out.println();
while(!won){
human.takeTurn(Setup.getBoard());
turns++;
Setup.printBoard();
if(Setup.hasWon(Setup.getBoard())){
won = true;
System.out.println("Congrats you won!");
}
if(turns == 9){
won = true;
System.out.println("Its a draw!");
break;
}
if(!won){
computer.takeTurn(Setup.getBoard(), human);
turns++;
System.out.println();
Setup.printBoard();
System.out.println();
if(Setup.hasWon(Setup.getBoard())){
won = true;
System.out.println("You lost!");
}
if(turns == 9){
won = true;
System.out.println("Its a draw!");
break;
}
}
} // close while 1
}
else {
System.out.println("Computer goes first!");
System.out.println();
while(!won){
computer.takeTurn(Setup.getBoard(), human);
turns++;
Setup.printBoard();
if(Setup.hasWon(Setup.getBoard())){
won = true;
System.out.println("You lost!");
}
if(!won){
human.takeTurn(Setup.getBoard());
turns++;
System.out.println();
Setup.printBoard();
System.out.println();
if(Setup.hasWon(Setup.getBoard())){
won = true;
System.out.println("Congrats you won!");
}
}
} // close while 2
}
System.out.println("Would you like to play again? Type 1 for yes or 2 to quit");
System.out.println();
if(s.nextInt() == 2){
playAgain = false;
}
}
}
}

想象一下你会如何在和朋友或单独玩的时候玩井字游戏，编写你用来玩游戏的算法并编写代码
-
@LuiggiMendoza 这就是我认为我所做的。我看不出哪里出了问题。这就是我目前遇到的麻烦。也许我在它面前呆了太久，但我看不到它。

您采取了哪些步骤来诊断非 AI 问题？可能值得休息一下，早上再试一次。
