Evalution or Alpha Beta problem

delphi_coder · Post by **delphi_coder** » Tue Mar 05, 2019 2:21 pm

Hi everyone,
After finishing some of the base parts of engine such as (Simple UCI Adapter)/MovGen/DoMove/(Simple fixed depth Alpha Beta Search)/QuiescenceSearch(excluding check moves) and very simple evaluation (as simple as material and score arrays for piece on position) I noticed that engine plays some crazy nonsence moves.
Now I wonder if it can be caused by evalution or a bug in search function.

Is there any free and ready to use evalution func that could be used as DLL function. I need such thing in order to test my search func and make sure every thing there is on their right way.

another question: Is bad sorting of moves for alpha beta search can cause wrong final result?

Move order will not make the engine play ridiculous moves. Are most of the moves nonsense or just the odd one? Can you post an example of a position and the move in question?

Bad move ordering will make the search take much longer, but eventually it should get the right answer.
Do you have a quiescence function? Sometimes bad moves are made when a quiescent search would have shown that the move fails due to a simple chain of captures.

A good thing to do to debug your evaluation is to take some positions and perform a 4-way reflection. The evaluation should be the same for all 4.

E.g.:

Code: Select all

Move order will not make the engine play ridiculous moves. Are most of the moves nonsense or just the odd one?

Other moves are not perfect and according to the engine strength are acceptable. but some of moves are buggy.

Can you post an example of a position and the move in question?

position startpos moves a2a3 d7d5 d2d4 g8f6 g1f3 c8f5 b1c3 f6e4 c3e4 d5e4 f3e5 f7f6 g2g4 f5e6 d4d5 e6c8 e5c4 c8g4 c4e3 g4h5 f1g2 h5g6 f2f3 f6f5 f3e4 f5e4 e1g1 b8d7 d1d4 d7f6 c1d2 c7c6 d4b4 d8d7 d5c6 d7c6 b4d4 a8d8 d4c3 c6b6 a1d1 e7e6 d2c1 f6d5 c3d4 b6d4 d1d4 f8c5 c2c3 e6e5 e3d5 d8d5 b2b4 c5b6 e2e3 e5d4 c3d4

for example in this sequence of moves, moves 25 to 28 seems wrong
My test chess engine plays black.

Bad move ordering will make the search take much longer, but eventually it should get the right answer.
Do you have a quiescence function? Sometimes bad moves are made when a quiescent search would have shown that the move fails due to a simple chain of captures.

A good thing to do to debug your evaluation is to take some positions and perform a 4-way reflection. The evaluation should be the same for all 4.

E.g.:

Code: Select all

I couldnt get what you mean 4 way reflection and how to use these FEN positions to test.
despite the fact that I couldnt fully understand the philosophy of quiescence function but yes. I implemented that from some available pseudo codes from the internet. Still I'm not sure why we have to throw engine thinking sequence to captures. I'm wondering what will happen if a move (lets say position) on the lowest node of search tree be perfect if and only if we will not fall ourselves to capture sequence.

The FENs are easy. Each of the 4 positions in a set should have the same static evaluation score, or there is a bug in your eval code.

Q-search is needed because the engine will play terrible chess if you leave pieces hanging to be captured at the leaves of the regular search. Q-search follows capture sequences until the the board is "quiet". No, it is not totally accurate, but it is a huge help. This gives your eval function a chance to be somewhat meaningful.

Okay, while black's 25th move (e6-e5) is not great it could be explained by a shallow search and/or simple eval function. White's 26th move (e3xd5) is the real blunder but that's not your concern. The remainder are not serious mistakes at this point.

The move by your engine worthy of investigation is 8...e6-c8 (should be d8xd5 winning the knight). The only explanation that jumps out at me is if your engine is only doing a 4 ply search before entering the Q-search at which point white can push the knights capture over the search horizon like so:

8...d8xd5 9. d1xd5 e6xd5 10. c2-c4

now we enter Q-search and the only captures are 10...d5xc4 (which loses a piece after 11. e5xc4) and 10...f6xe5 (and white responds 11. c4xd5 and material is about even). So basically black either plays 10...f6xe5 or stands pat. Either way material is about even and it can't see that the knight can't move and will be captured on black's next move.

So is the main search only to depth 4?

Regardless there are a couple of things you will need to do as you go forward to debug these types of situations. First and foremost you need to have confidence that you are generating all the correct legal moves in any situation, so have you written a PERFT function so you can test that? Thats unlikely to be the problem in this case but in the future you will have plenty of confusing moves and the last thing you want to worry about is wether your MoveGen is corrupted. And secondly when you finish the search you want to display the PV with the best move and the score. This way you can see how the engine thinks play will continue, which can often give you clues as to what is wrong.

Yes, exactly. because i just set that to search very limited fixed depth since there was no improvement to raw alpha beta such as move ordering or PVS or any pruning techniques.

I thought about many kind of ways to implement good search but some are not possible due to memory limitation and some idea's was hard to implement.

one of the simple idea's i read somewhere is incrementing src square to dst square for any ply. how is the efficiency of this way
