Hello to everyone ; I'm a newcomer in this list and computer go
programming. I have a chess programming background, but I want to
start something new. :-)
I'm currently in the early phases of developing GTP compatible go
engine ; now it's time for me to choose a board representation : are
there some articles or tips on this ?
i've only fooled around with this a /little/, bit at the lowest level,
but i would start with something like below.
i suspect there is a lot more stuff that can be precalculated for a
particular board size.
thanks
public class Go {
enum Color {
black,white,vacant,edge; // edge can be useful
}
enum Direction {
n,s,e,w,ne,nw,se,sw
}
class Neighbors {
Neighbors(int width,int depth) {
this.width=width;
this.depth=depth;
this.size=(width+2)*(depth+2);
n=new int[size];
s=new int[size];
e=new int[size];
w=new int[size];
ne=new int[size];
nw=new int[size];
se=new int[size];
sw=new int[size];
// lots more init required, but it this is constant for any
width and depth
}
final int width,depth,size;
int[] n,s,e,w,ne,nw,se,sw; // index of neighbor
}
class Board {
Board(Neighbors neighbors) {
this.neighbors=neighbors;
colors=new Color[neighbors.size];
}
final Color[] colors;
final Neighbors neighbors;
}
}
