Furthermore, I'm also disappointed with the initial tests: Using v3.3 dll and 3-4-5 men bitbases -------------------------------------------------------------------------------- Analysis of C:\Documents and Settings\Administrator\Desktop\CHESS\EPD\Uski.epd Analyzing engine: TogaII14-5c-1cpu 6/20/201...

We're running out of luck then . No wonder these code projects were left 2 yrs. ago without even being publicly released.

I had used the new egbbprobe 4.0 included and compiled a 64-bit dll for testing (to see how it responds). Sad to say it can only load the 3-4 men (in 5 seconds) using Scorpio 2.7 (32/64 bit). When I tried 3-4-5 men, Scorpio just displays "Egbb loading" and stays that way. Version 3.3 as an...

It's good to know, thanks.

I already sent a pm to Daniel Shawul (@ CCC) so that we could test whatever 6pc base files it generates.

Just to update,it was only today that I saw the 6 pc bitbase being created. But sad to say it only created kqqqqk, krrrrk, kbbbbk as examples and the rest were empty bases due to to memory allocation failures based on the log file. Some 6pc need more ram and failed as I'm using the pc memory for oth...

You're right. I have no idea how big will it be.

Daniel Shawul may need to modify the probing code if ever a 6pc database is available to test.

(BTW, I was not worried by the diskspace as I still have enough but the ram memory.)

Thanks.

Ray wrote:It is working here, but as with you, it is on the 5-men at the moment. It seems pretty slow.

Yes, it is slow. I hope my 4 GB memory is enough when the 6pc comes.
I'm still on the 5pc generation stage too since yesterday evening.

I just gone home and tinkered a bit this new 6 piece bitbase generator code by Daniel Shawul. https://github.com/dshawul I can't find yet a specific command parameter to adjust but it works instantly! Just execute in console mode and it generates and compresses automatically. I'm still on the 5pc. s...

Thanks pal . Missed that thread!

I'm sure some have heard about these, but I got no response at CCC from this thread: http://talkchess.com/forum/viewtopic.php?t=26184 I came across these two utilities while studying chess engine in endgames and looking for other tablebases aside from Scorpio' bitbase: Hoffman: It's an open-source t...

Any info about this new bitbase format from Chessbase I'm hearing at CCC? I can't google enough data about this except for a 'demonoid' link :D! At least it says, " New fritzbases for Nalimov Bases ". It's probably similar in usage as the private Shredderbases but also an interesting subje...

Since Shaun is on holiday, I decided to release the new builds of the old sources in our TDDB public forum. Check them out here: http://www.computerchess.info/tdbb/phpBB3/viewtopic.php?f=9&t=139 Jerry Donald made it work on his new betas. I only ported the changes for the old Togas for public us...

Denis - While aware of the program Chesterfield, I can only guess at decoding "CL" and fess ignorance to ask: what is the ChesterfieldCL project? From your perspective, are there any shortcomings to converting the Nalimov tables to bitbases? john Honestly, this project is just a special i...

Thanks guy for the infos. It is really better nowadays to just acquire the generators of these databases as most hardwares nowadays are very fast. I just wanted to have CW endgame databases for my ChesterfieldCL project. The old EGT's have some flaws, that's why Nalimov's EGT is still the most relia...

Werner posted some results on CCC - 64-bit is 10% faster, not very much Yes, you are absolutely right. When the Scorpio 2.0 src was released, I already tried compiling a 64-bit version and was still unsure of myself because there was not much improvement in speed. Since 64-bit is new to me, I'd jus...

I spoke too soon. Jim already made a much faster compile than mine based on news at CCC. Master Jim does it better though! Just informing. I better look for some ways to improve mine :wink: and probably look for a way to tweak the code so that the dlls/bitbases of 32 and 64 bit will not be transferr...

Take note also that Scorpio takes a very long time to complete its initialization during each start-up. I tested a 64-bit Toga 1.3.4 with egbb, and it initializes faster using the same 64-bit egmprobe dll. This maybe the reason why Scorpio takes a long time to start a game. You'll have to wait till ...

Thank Daniel Shawul for sharing the source for his egbb.dll probe. You can now build egbb.dll for your OS (32/64 bit). Just request and I'll compile one for any Windows platform. Hi Denis, if you have the time a 64-bit compile of the egbb.dll and Scorpio 2 would be fantastic - we can then see what ...

I already mentioned this to Jim Ablett as he is one of the official compilers of Scorpio, But I'll build one for you nuch the the same as Jim's compiles. The 64-bit egbb.dll goes with it too as prerequisite -tried and tested.

If we had code to generate 6 piece scorpio bases and are usable by Scorpio and various other engines that have implemented the Scorpio BB's I would happily devote some CPU time to the generation... Shaun Many thanks Shaun. I'll upload a link for the old (v1.0) bitbase generator bundled with the new...

Sorry for the late response, but I guess Daniel Shawul is the right person to ask. I'm as interested as you are since the bitbases of Scorpio are the best in this area - and fast too. I have tried generating the 3-4-5 men before using the old code (v1.0) but stopped as the 5-men were released. Since...

Edwards, Wirth, and Heinz are also the best contributors in this endgame studies. The generated endgame tables of these individuals maybe too old yet still useful for study. I hope somebody has or knows where to get these egtbs of Chris Wirth. All the old archived sites and email address are already...

As I'm fascinated with these different chess endgame databases/ I came across an older chess engine, ChesterfieldCL which uses Chris Wirth's endgame tablebases. Has anyone have an idea where to get his full generated tablebases in sdb format? His old sites were already obsolete.

Hi all I need a compilabe code for probing 6-men tablebases.I had saw probe.txt in some tbgen packages but I got hundreds of errors... regards I remember about Sune Fischer's egtb.dll code (of Frenzee) which has a similar approach. I t was removed on his new site but I managed to find a similar one...
