Maybe better way...but that is no guarantee. (Stockfish version)

Code: Select all

			if &#40;Score > BestScore&#41; &#123;

				BestScore = Score;

				if &#40;boardPly == 0 && &#40;LegalMove == 1 || Score > alpha&#41;) &#123;
					UpdatePv&#40;currentMove, Score, depth, alpha, beta&#41;;
				&#125;

				if &#40;Score > alpha&#41; &#123;

				BestMove = currentMove;

					if &#40;Score >= beta&#41; &#123;
						// history, killers
						return Score;
					&#125;
					alpha = Score;
				&#125;
			&#125;
		&#125;
Do the engines use the upper bound value (and move) for the best move or not?

Right way? (Stockfish does not use it)

Code: Select all

			if &#40;Score > BestScore&#41; &#123;

				BestScore = Score;

				if &#40;Score > alpha&#41; &#123;

				BestMove = currentMove;

				if &#40;boardPly == 0&#41; &#123;
					UpdatePv&#40;currentMove, Score, depth, alpha, beta&#41;;
				&#125;
					if &#40;Score >= beta&#41; &#123;
						// history, killers
						return Score;
					&#125;
					alpha = Score;
				&#125;
			&#125;
		&#125;

Or do not use the value of the pending search?

What do you recommend?

thx, Tamás

Regarding your code snippets, I'd definitely recommend to only update BestMove (at root) and PV (everywhere) if bestScore > alpha. Not doing the latter might have less impact but not doing the former can end up in playing an inferior move if you run out of time before finishing the re-search after failing low.

Stockfish (looking at SF9 source) does both updates only if bestScore > alpha.

I can't tell whether that is related to the behaviour you have observed, though.

Hi Sven!

Stockfish use this for the root (best) move updating:

Code: Select all

      if &#40;rootNode&#41;
      &#123;
          RootMove& rm = *std&#58;&#58;find&#40;thisThread->rootMoves.begin&#40;),
                                    thisThread->rootMoves.end&#40;), move&#41;;

          // PV move or new best move ?
          if &#40;moveCount == 1 || value > alpha&#41;
          &#123;
This is what I do..

I do not use any cut/pruning in the end game only the LMR and See pruning at Qsearch..

The aspiration window varies wildly at the endgame (promotion).

Now I check that the hash entry (best move) and the saved best move is equal or not at end of the search...

Hi, the error might be that you did not update the position correctly when he took your pawn on f7. If you did not update the enemy king move correctly you would have the enemy king on e6 and taking his pawn would be illegal. If that would be the case your king move would be logical.

Hi Pio!

This is impossible, because the previous iteration was good and second time there was no problem..
The error is due to time cutoff and the score is not exact..and the aspiration window.
The question is how can this be avoided?

If it is due to time, make sure that you aren't backing up scores still if you have told your engine to do a quick exit. You can only trust root moves that were searched completely. The move you exit early on because of time will get a bogus score backed up, and you don't want to use it.

Hi Robert!

Did you think of this? This cannot be a problem. (IMO)

Code: Select all

			makeMove&#40;);

			AlphaBeta&#40;);

			unMakeMove&#40;);

			if &#40;timeStop == 1&#41; &#123;
				return 0;
			&#125;

			if &#40;Score > BestScore&#41; &#123; .....

I took another look at the PV output in your original post. To me it looks as if iteration 19 was not completed due to first failing low, then failing high, then failing high again. Then timeout came and you returned the "best move" of iteration 19 which turned out to be an arbitrary bad move (Kc3).

I can only tell you how I deal with the "best move" problem at the root node in my engine Jumbo. Stockfish has a completely different structure which does not help me here.

At any time during search I maintain a "best move" at root that could be played in the game when search would be interrupted. Let's call it BM. It is updated whenever I am sure that this is correct and necessary. Now let's say iteration 18 has completed, and BM = Kxd5. Time is not exhausted yet so we start iteration 19. BM is unchanged. First move to search is Kxd5. It fails low, so the new iteration did not deliver any new information yet. BM remains unchanged, and a re-search occurs with a different window. Now the re-search fails high. In Jumbo I do *not* update the PV (neither at root nor down the tree) if score <= alpha or score >= beta, so even now BM is unchanged! In your case there was another re-search that failed high again and delivered Kc3? as PV move, this is dubious for me but even then BM should remain unchanged so that on timeout (which occurred in your example) I would play the BM that had been found in iteration 18, while no new PV move had been found so far in iteration 19.

There is kind of a "definition" that a move can only become PV move if its score is within the alpha-beta window. If Stockfish does something different at the root then it may be correct for Stockfish (probably for very complex reasons which I do not try to understand at the moment) but for me it is "against theory".

I suggest that you also check why the second fail-high in your iteration 19 can return a different "best move" than the first one but with a lower score. I would expect another bug somewhere in the search, maybe in the aspiration window code?

Thanks your answer!

As i wrote, i do not cut anything in the pawn endgame, only in Qsearch (See pruning)

Maybe there's going to be a problem? (Qsearch)

Here is my PVS code:

Code: Select all

			if (&#40;is_pv && LegalMove != 0&#41; || R != 0&#41; &#123;
				Score = -AlphaBeta&#40;-alpha-1, -alpha, depth+E-R-1, true, Check&#41;; // PVS-LMR
				if &#40;Score > alpha&#41; &#123;
					Score = -AlphaBeta&#40;-beta, -alpha, depth+E-1, true, Check&#41;; // Full
				&#125;
			&#125; else &#123;
				Score = -AlphaBeta&#40;-beta, -alpha, depth+E-1, true, Check&#41;; // Full
			&#125;
LMR is work in endgame also.


And here is my ASP:

Code: Select all

		search &#58;

		for &#40;currDepth = 1; currDepth <= maxSearchDepth; currDepth++)
		&#123;
			if &#40;countMove == 1 && currDepth > 5 && bestMove&#41; break;

			for &#40;var margin = &#40;currDepth >= 4 ? 10 &#58; INFINITE&#41;; ; margin *= 2&#41; &#123;

				alpha = Math.max&#40;Score - margin, -INFINITE&#41;;
				beta  = Math.min&#40;Score + margin,  INFINITE&#41;;

				Score = AlphaBeta&#40;alpha, beta, currDepth, true, inCheck&#41;;

				if &#40;timeStop == 1&#41; break search; // time out

				if &#40;Score > alpha && Score < beta&#41; break;
			&#125;

Interestingly, I can not reproduce the mistake. Maybe is there a mistake in the transposition table? (collision)
