5 years ago When I paste the commands shown in the debug log, the issue doesn't reproduce, so I'm not immediately sure what's causing the issue. Which exact binary are you using?

5 years ago Ignore that, I'm now able to reproduce. I understand the problem and will work on getting a fix.

5 years ago The 64-bit (POPCNT) one, CRC-32: 5E1414A5. I just retested with Hash sizes 256, 128 and the default 32. Same illegal move a1a1 in every case.
edit: Ah, I've been ninja'd. ;) Standing by for the fix.

5 years ago I rolled out something I believe should fix the issue. I'm not 100% confident in the robustness of the patch, so I'll look into it more when I get some time. If this doesn't fix it, I know how to do so. Can you confirm/deny that the fix worked?

5 years ago Need a Makefile for Windows, something that would work with MSYS2 and Cygwin. Tried making my own and got tons of errors.

5 years ago I was planning on adding a Makefile at some point, but for me copying and pasting the compilation works fine. Regardless, I actually updated the files under Release 1.2.1. Should have mentioned that.

5 years ago The new exec (CRC-32 388D09A3) doesn't fix it. Besides the usual 40/4 and 512 hash I tried 40/20 and 32 hash, same result (a1a1).

5 years ago Interesting. I'll take a look at it in the morning. Thank you very much for being patient with me and for reporting this bug.

5 years ago No problemo.
An interesting find: if you start the game from the position where it wants to play a1a1, it chooses to play the queen back to d1 and the game goes on:

5 years ago The heart of the issue is that apollo checks if the current position is a repetition, and if so, it returns to cut down on the search time. The problem is apollo previously checked if there was a transposition table entry for the current position, and if so it returned. When outputting the best move, however, apollo uses a triangular pv array. The array was never filled in that case.
I just threw together a fix to fill the pv array in this case, however I'd like to look more deeply at this issue and related ideas to make sure I didn't miss anything when I get more time. I tested the exact commands you used before that caused apollo to return a1a1, and I now get the move a4d1.
Could you confirm that the new patch(binarys under release 1.2.1 also updated) fixes this issue?

5 years ago Great, now it's fixed.
There only remains a slight issue of nodes, NPS and time all displayed as zeroes for every iteration of the very last move (4.Qd1).

5 years ago Another example found, possibly unrelated to those reported previously. It took 80 games to surface.

It would also appear that v1.21 is considerably stronger than v1.1. That's probably not a bug.

5 years ago Still looking at this, not easily reproduced by me. Just settings up the last position and running a search didn't output that move for me, so my best guess is it's an issue with the transposition table. Sorry it took me so long to respond.

Clearly there's some debugging still to be done. :>

5 years ago Curiously, all five disconnects occurred when 160 moves have been completed for both sides, with Apollo playing black. Another game ended after 159 moves in a stalled connection. Apparently Apollo cannot last longer than four 40-move playing sessions.

5 years ago And now for something different -- Apollo achieves a completely winning position (mate in 6) and its eval goes completely haywire. 30 moves later the game ends in an illegal move.

2 years ago https://github.com/TheBlackPlague/StockNemo/pull/10 - I am developing my own chess engine, StockNemo. Is the lack of ELO on Apollo's part because of that? StockNemo shouldn't be 2K ELO right now (AB-Search, MVVLVA/Promotion Move Ordering, Mate Distance Pruning, Draw Pruning, Transposition Table, Material + PSQT Evaluation, QSearch, Null Move Pruning) ... what are your thoughts?
This is a continuation of #7 . The good news: the Hash option now works as expected. The bad news: illegal moves are still there.
