World Draughts Forum

Sorry, I have to repeat the entire match from the beginning. As for the Bucket-size option, I think you gave me that and not Bucket-shift as you wrote - I have to check it because I have everything on the hard drive.


The ini file is still on my FTP-server, it shows:

threads = 16
tt-size = 32 ...

What on earth is 'TT-size = 16'? That means it used a hash-table of 65 KB, does not seem very appropriate with 16 threads sharing the hash-table.

That version of the engine does not know 'Bucket-size', it should be 'Bucket-shift = 2', it clearly was in the ini-file when I sent you this engine ...

@Joost: i saw your perft benchmark hitting over 1 billion per second. Do you just count the possible leaves, or do you generate the positions as well? I can't image making my generator a factor 2 faster.


My move generator normally creates a list of moves. For capturing moves, I count the number ...

In my opinion, creating a strong Draughts program depends largely on the dataset you use to train the evaluation function.
If you manage to get AI to generate a dataset for you as well, it might be possible to generate a strong Draughts program using AI.
The rest of the program, such as the move ...

I think it is because the engine under DXP does not receive any information about the increment. Therefore, the engine does not know that it gets an additional 1 second per move with a 1-second increment. Toward the end of the game (when it thinks it has almost no time left), the engine starts ...

Without increment GWD's hub and DXP reported time-used/time-left in the log-files are pretty much in sync with the GUI reported time-used/time-left (within a second). I don't think GWD handles increments at the moment, so these would be ignored bonuses.


Maybe timings are right when you run ...

Most of it seems to be working, but I have the feeling that there is still something wrong with the timing. When I play games of 1 minute with an increment of 1 second, it often happens that the engines have more than 2 minutes left on their clock at the end of the game.

DXP doesn't allow a Fisher ...

Obviously an overflow somewhere. According to Ares the position before 58. --- 49-40 is a draw and not a win. The question remains whether plus-500 would have been able to keep it a draw.

I could not retrieve the final score. Think we need Ed for this. But anyway this was an interesting game. And between move 25-30 Plus was even in the plus. Not sure the position was winning.


You don't need an 8P EGDB or more to solve the final position, Ares with 7P sees in 11 seconds that 66 ...

What happened in the last game of round five Flits vs Plus 500? The final position is obviously a draw, did Plus 500 lose on time?

I am running Codex locally but I did not expect it to search my entire drive if needed:


It's also searching your harddrive if not needed. All these 'Big Tech' companies are spying on you, this is something you have to live with. I've blocked most of the URL's in my firewall where telemetry is ...

Good point, currently 'go ponder' behaves as 'go analyze'. Perhaps we can have a quick show of hands here: do all engines support 'go analyze', so when browsing a game the GUI continuously sends 'go analyze'? 'go ponder' should work as Harm/UCI mentions?

Normally with UCI (when pondering is ...

BTW, I sent you an email about the PC, one thing you could try.

I don't expect a program like Dragon to make such an error with a 8p DB, and 32 core search process.
So I though or the computer had a problem, or Dragon has a bug.
Not impossible that Michel was not able to test 32-cores, so the program still has an issue with this number.



Ares agrees that ...

I have to wait a few days. Then I will know everything. I never overclock either the processor or RAM. The worst thing is that now it is difficult to buy new RAM. I have 8 sticks of 16 GB RAM.

I don't mean explicit overclocking, but if by any chance EXPO is enabled in the BIOS it ...
