In the engine I've been working on for a week or two (I'm brand new to
computer-go)
I use:
typedef int INTERSECTION;
typedef enum { BLACK, WHITE, EMPTY } COLOR;
struct GROUP
{
INTERSECTION base;
COLOR color;
int count;
int liberties;
INTERSECTION children[5];
INTERSECTION parent;
};
struct BOARD
{
COLOR side_tm;
COLOR board[BOARD_SIZE * BOARD_SIZE];
struct GROUP group_list[BOARD_SIZE * BOARD_SIZE];
struct GROUP *group[BOARD_SIZE * BOARD_SIZE];
int group_count;
int real_group_count;
INTERSECTION empty_list[BOARD_SIZE * BOARD_SIZE];
int empty_index[BOARD_SIZE * BOARD_SIZE];
int empty_count;
};
I've just finished implementing the basic rules. I'm now working on
detecting the end of the game and scoring. I think this is a pretty
standard data structure. I do know that bitboards can be used, with
one integer usually representing a row.
