Recently I have implemented a function to reverse the color to play in a given position (and to symmetrize the position also i.e. if white have a queen on b2 in a position, black will have a queen on b7 in the symmetrized position), which can be used in test suites as they are known to be very useful to detect bugs.
This function is itself without bugs :wink:

.
But I found that the search (number of visited nodes in Alpha_Beta, and score for an iteration) is not symmetric if the color to play and the position are reversed. When I use a simple material eval then only the number of visited nodes are just slightly differents. My full eval seems without bugs as far as i know, though it is very complex and may still have some (without bugs=symmetrical for both sides of course).
I have no null move and no transposition tables.
Trying to understand that I played with LMR and found that avoiding to reduce tactical moves reduced the difference of search between a position and the symmetrized position (ok it is good to do that but why could it cause such large effects).
As far as I understand doing the modification above on LMR tends to reduce the difference of search between a position and a symmetrized one.
Before to come to the conclusion, please look at an example on this
initial position :
1k1b3r/ppp3p1/3p1p2/3Pr2q/P2N3p/5Q1P/1PP2PP1/1K1R3R w - - 40
[diag]1k1b3r/ppp3p1/3p1p2/3Pr2q/P2N3p/5Q1P/1PP2PP1/1K1R3R w - - 40[/diag]
it is a well known position given by kostyev and the solution is
Nc6+
Here is the result of Milady search when allowing captures in LMR

this search result is much more consistent with the one of the symmetrized position.

Now i come with the conclusions, and i would be very glad to have
your advice

. In fact I'm completely lost and have no good explanation for this behaviour, so if you observed something near
in the past, please give me your advice. Also, is it normal that
a search may be unsymmetric?

Sorry for that long description,

Perhaps your move generation order is different for white and black? Like in the initial position if it is white to play first, you might generate a4, b4, c4 ... but if you make a symmetric position and have black play first it might generate a5, b5, c5 which is not a symmetric order of generation. So perhaps this could be the difference?

Hi Pradu !
You are really quick in answering ! :wink:

I must admit it is one point I thougt about (as you mentioned, the move generation is different when it is btm or wtm).
One explanation could be that some moves are generated in different orders, then in certain cases (especially when we are in unsorted tree, i.e. no differences between most of the moves generated), the search could not be able to bring good moves in good ranking positions (so the moves will be reduced by LMR). Note that there lot of places where the moves are examined differently from white or black point of view (attack tables, evaluation,...) but the only place where it could have an impact seems in the generation process. I am really amazed of the impact of the order of generation of moves, if this explanation is the good one.
Note also that a perft test reported the same exact number of nodes for a position and for the reversed one.
Thanks for your answer !

LMR reductions for black may be a problem.
Look at the decision process when side to move is black.
Otherwise, the output does not make much sense, especially since it is easily solved without LMR.

by **YvesLejeail** » 20 Aug 2007, 17:53

It is not so clear for me but it seems rather due to an assymmetry
when scanning the board (wtm or btm, the board is always scanned
in the same way, from a1 to h8). The moves are thus not generated
in the same order, for a position, or for the symmetrized one.
This difference of order of move generation could have an influence on
unsorted moves :shock:

(just a theory, feel free to correct me if it is wrong :wink:

). Finally, the LMR just reduces the moves that
are too far away after sorting. Without LMR we should see noo differences at all (but maybe i'm wrong there also, and I'm too lazy to verify again this detail

).

I agree. Changing the move order inside the search can produce large or small changes in the number of nodes searched, and due to hashing can even change the score or best move if multiple moves are very "close" in final score...

This problem can be solved, but the solution slows things down too much to be used by most of us.

Hi Yves,

it sounds like you are not maintaining a piece list, which requires scanning the whole board frequently even if there are only a few (relevant) pieces present. But even without a piece list it should be possible to efficiently define a scanning order for btm which simply reverts the ranks 1..8 for wtm into 8..1 for btm.

Perhaps take a two-dimensional array scanSq[2][64] which you initialize and use like this (you will definitely do better 8-)

):

Code: Select all: int scanSq[2][64]; // init code static int const scanStart[2][8] = { {A1,A2,A3,A4,A5,A6,A7,A8}, {A8,A7,A6,A5,A4,A3,A2,A1] }; for (int r=0; r<8; i++) { for (int f=0; f<8; f++) { scanSq[WHITE][8*r+f] = scanStart[WHITE][r] + f; scanSq[BLACK][8*r+f] = scanStart[BLACK][r] + f; } } // move generation code for (int i=0; i<64; i++) { int sq = scanSq[activeColor][i]; if (isSqrOccupiedBy(sq, activeColor)) { generateAllMovesFrom(sq); } }

and try whether this helps to avoid symmetry problems.

The problem is, you don't want to do that. There is an optimal way to generate moves for each side. Always toward the center is one example. But for bitboards, we really have only two directions, find the MSB or the LSB. And that is not fully symmetrical when you flip sides...

fixing it would cost more than it is worth.

This problem can be solved, but the solution slows things down too much to be used by most of us.

Different move orders can blow up the tree (conceivably increasing the node count to its own square in the worst case) but the program should still get the same answer when it completes the same depth. If it gets a different answer, then there is a bug.

Thanks for all the answers !
Yes i have no PieceList and must scan the board to gen the moves for instance. I agree Sven that it must be possible to symmetrize the move generation, but don't want to enter into that cause I guess "what to choose as reference"? I prefer to live with that. Now that I know that it is possible to have different nodes when generating moves in different orders, I have the answer to my question

So the most important thing for me now is to force the search to avoid to reduce some "important" moves. At this time I do not reduce in LMR:
- captures (good or bad)
- passed pawn moves
- when in check, or when giving check
- ... (other to add, but will look again at some old threads before)
At least, for these kind of moves I should not see the strange behaviour I had before.
Finally Dann, I agree that the strongest engines do not have this behaviour, but we are not in the same class

. Their search is way smarter than mine. Will try the positions you posted.
Thanks again,
Yves

My engine extends a move if all other options lead to forced mates.
This extension is certain to be triggered if this move is ordered after all moves for which this information is not available before starting search at current depth.

Another example where move ordering is significant is every situation where an evaluation is obtained from hash (although, strictly speaking, this may be considered a bug because it seems hard to handle draw scores correctly when relying on data which depends on a different move history).

This difference of order of move generation could have an influence on
unsorted moves (just a theory, feel free to correct me if it is wrong ). Finally, the LMR just reduces the moves that
are too far away after sorting. Without LMR we should see noo differences at all (but maybe i'm wrong there also, and I'm too lazy to verify again this detail ).
Yves

I agree. Changing the move order inside the search can produce large or small changes in the number of nodes searched, and due to hashing can even change the score or best move if multiple moves are very "close" in final score...

This problem can be solved, but the solution slows things down too much to be used by most of us.

Different move orders can blow up the tree (conceivably increasing the node count to its own square in the worst case) but the program should still get the same answer when it completes the same depth. If it gets a different answer, then there is a bug.

You can't even bet on that. Minor changes to move ordering will change the depth that you find the key move in fine 70 for example.

The way to solve fine 70 early is to try a less-than-optimal defense for black, so that white can find a way to win a pawn. But then by trying the optimal defense, you now find in the hash a way to win the resulting position. But if you reverse the order of those two moves, now you won't find the solution at all at this depth.

Changing scores is not that uncommon because of how the hash table grafts scores from one part of the tree to another.

Fine 70 is a really good test for this as well as hash table implementation correctness.
