Hi, Thanks, since the post I've been doing some more work, and some more thinking on the subject. You are right, obviously, that ignoring e.p. rights will not work. I am treating pawns the same as any other piece, so no pawn slices, and I have made room in my data structure for two values, if there ...

Hi again, One thing I have been putting off, but which I can no longer avoid is e.p. captures. :) I have been thinking about just ignoring them during generation, and then do a two (or three) position lookup when an e.p. square is present in the lookup request. Is that the way to handle it, or is th...

Hi, I posted a question about a data mining tool for tablebases a while ago. There has been no answers, and since I have just had a breakthrough with my own generator (bug hunting for quite some time, finally nailed the bug that had me pulling out my hair), I have decided to expand my project with j...

Thanks, I finally found that damn bug :roll: I can now generate bases with pieces on both side (other than the black king) One more thing, though: During generation I am also encoding multiple pieces of the same type and color (up to 4 pieces) as one "piece configuration", that shouldnt ma...

Hi, As mentioned in another post, I am back to working in my own Endgame generator again. The method as posted by Syzygy earlier is working like a charm. I have managed to get a working 3-piece generator (I think) at least I have not found any bugs yet. I am using the a1-d1-d4-a1 triangle scheme whe...

Hi, I am back working at my own tablebase generator, which is using DTM metric. I am looking for a tool to help me debug a few problems, and I am hoping that someone here has a tool, or knows of a tool, that can extract all positions from a given tablebase with e.g. mate in 3, and put the positions ...

Hi,

Thanks for your reply, I'll keep working on it.

About symmetrical material: I was not talking about using it during generation, only to save space after generation is done. Thanks for confirming hat it works.

Hi, Thanks for the algorithm. Sorry for being so long to reply, but I have not been working on the generator for several month for personal reasons, and now I am trying to get back up to speed. I have tried your method, but I cannot seem to get it working. I have been debugging for quite some time n...

Hi Kirill, Thanks for replying. The description you point to for the "Grandfather method" leaves some questions. First of all, I dont understand the part about it being illegal to start in check... If the side NOT to move is in check, the position is broken, right ? Otherwise legal un-move...

Hi, First off: sorry for this rather long post. I know there are a lot of tablebase formats out there already, but I started ny own little project, to get a better understanding of the process. Also I am learning C# as a bonus (I know it is not as fast as C++, but I want a GUI, and that was a lot ea...

Hi, This might be a bit off opic, if deemed so, please forgive me. I have been trying to make a program using the .DLL from the RetroChess generator package. I built a small project in Visual Studio, tring to probe a 3_KP-K.tby position, but all I have managed to get is an exception error in the .dl...

ok, I'll do that, then. Thanks. The generator works like a charm, and I have all 3+4+5 man classes generated. Good work on your part. I tried generating KQQVsKQQ on my 12 GB system, but the swapping immediately bogged my PC down, so I had to give up on that :x A couple things, I've been thinking abo...

Hi again, I have made my own winodws batch file to make the tables. That generator is FAST! :-) Verifying the generated tables is good... Only problem for me is that the package you attached only contains the generator, and the verifyer is a different program if I read the Perl script correctly. Wou...

Awesome!, thank you very much!!

Hi, I've been out of computer chess for a few years, but I am trying to get back up to speed. I am still thrilled about endgame tablebases, so this new format is of great interest to me. I am no C programmer, nor familiar with linux, and/or gcc, so a simple question: Is there anybody who has windows...

Hi Guido! I have a couple of questions: 1) Does your TB generator already support generating 9-men TB's ?? 2) Are you planning to release a compiled version of the generator for Windows (either 32 or 64 bit) ? 3) Is it possible to download some already generated TB's anywhere ? Keep up the good work...

Hi Andreas!

Are you using a High ID in Emule ?? Otherwise you are cutting yourself off from a lot of sources.....

Hi Kees! I am also downloading and sharing (many), but strangely my downloading is much slower than the uploading. Normally it should be the other way round. The upload is at his maximum of my connection (110k) but my downloading is only 1/3 and lower (10k-60k) while my connection is around 1000k !!...

Hi!

Maybe it would be a good idea if Kirill took those instructions and put them on the index page, to help new downloaders to a good start ??

Hi Thomas!

A very good idea, I have configured my EMule to the same settings here.

Yes they do

Hello Guy! I think Wulf is missing the point. The scenario to test is the one where the KRPKR EGT is available but the KQRKR EGT is not available. I'd be surprised if Arpad is right: I think some engines are 'tricked out', and more likely in earlier versions of these engines, by the fact that [as in...

Hi! Just tested the position above with all 3+4 man and krpkr available to Gandalf. It wants to promote to a queen, and reports a mate in 15 after eq=Q Rxe8 Rxe8. How is the problem supposed to show up?? Do I need to remove the 3 & 4 man bases too, and only have krpkr available, or am I complete...

Hi Andre!

Will there be a new version of Wilhelm available ??

Hi!

How is the verification process comming along ??
