TRON: Thuật toán AI của trò chơi?

Xe máy hoặc bất cứ thứ gì nó được gọi là như thế.

Cho một mảng 2d đại diện cho bản đồ trò chơi, trong đó mỗi phần tử có thể là 0 hoặc 1 (0 đại diện cho không gian trống và 1 đại diện cho không gian đầy), thuật toán được sử dụng cho AI của kẻ thù TRON là gì?

Tôi chưa có cơ hội tìm hiểu mã của họ, nhưng Armagetron Advanced là một trò chơi chiến đấu nhẹ nhàng tương đối nguồn mở.

Bạn có thể tìm thấy nguồn (và các tệp thực thi) tại đây: http://armagetronad.net/doads.php

Đây là chủ đề của một trong những cuộc thi Google Ai

Có một số tài nguyên tuyệt vời từ trang đó:

Tôi không biết bất kỳ thuật toán nào nhưng tôi có thể tạo một "thuật toán" đơn giản trong java

//2D boolean (true/false) array
boolean map[][] = new boolean[20][20];
//this represents the position of the AI on the map
int x = 10, y = 10;
//this int will be 1 - 4 and will represent a direction
//1 - up
//2 - right
//3 - down
//4 - left
int direction = 1;

void init(int startX, int startY){
    //set the x and y to a starting position
    x = startX;
    y = startY;
    //this will set the entire array to false
    int i = 0, j = 0;
    while (i<20){
        while(j<20){
            map[i][j] = false;
            j++;
        }
        j = 0;
        i++;
    }

    //and this will set the starting position to true
    map[x][y] = true;
}

void tick(){
    try{
        //try to go straight and will error if 
        //it cannot because it would be out of bounds
        switch(direction){
        case 1: //up
            if(!map[x][y-1]){ //will error out here if the block in front is out of bounds
                map[x][y-1] = true;
