Subject: Hmm... the mystery remains...

Go up one level in this thread


Now I've done some testing with smaller values...

Using these constants increases the nodes searched by 5%
#define DOUBLED_PAWNS -1
#define PAWN_NOT_ISOLATED 1
#define BOTH_BISHOPS 1
#define ROOK_HALF_OPEN_RANK 1
#define PAWN_CLOSE_TO_KING 1
#define QUEEN_CLOSE_TO_OKING 1
#define KNIGHT_CLOSE_TO_OKING 1

Using these constants increases the nodes searched by 30%
#define DOUBLED_PAWNS -5
#define PAWN_NOT_ISOLATED 4
#define BOTH_BISHOPS 10
#define ROOK_HALF_OPEN_RANK 4
#define PAWN_CLOSE_TO_KING 3
#define QUEEN_CLOSE_TO_OKING 4
#define KNIGHT_CLOSE_TO_OKING 5

Obviously anything I do makes the node count go up, and the basic questing
remains, isn't that wrong?

Or is the problem that I've only done very little evaluation and that this is to
little and this "confuses" the engine?
