>  Analysis is another story. I've been trying it in some cc games and it's promising.


In IDEA or IA?
Parent - - By keoki010 (Silver) [us] Date 2011-02-22 21:36
Just IA so far.
Parent - - By TheHug (Bronze) [us] Date 2011-02-22 21:39
Have you ever mess with engine settings. When using IDEA? It sounds like a dangerous prospect unless you know what you are doing.
Parent - By keoki010 (Silver) [us] Date 2011-02-22 21:50
I've played with a couple of concepts. However let me say that for CC an I stick to tried an true proven things. :smile:

Yep, I love it too and no you don't really need the TB's.  The reason for the time loses with TB's on my system is probably that I've got them on a SATA disc and it's maybe too slow.

Oh, here's the pgn!  Some good games with very few time losses.

Thanks.
Parent - By keoki010 (Silver) [us] Date 2011-02-22 22:53
Uly, look at the ends of all of the games.  Something seems to be wrong.  I used Arena 3.0 for these but it looks like something switched the endings around and the wrong program won.  I was looking at some of them at the beginning of the pgn file.  Might be that I've got something setup wrong in Arena.
Parent - By keoki010 (Silver) [us] Date 2011-02-16 18:24
yes, I saw that post.  I left a post for him with a fragment of a game that hangs the TB stuff in the endgame.  It won't give a pv most of the time. It will show d=1 and a single ply. It does superfine in opening and middle games.

Nice project, are there also 32bit-compiles of PAMC_GTBg or PA_GTB_Gran2 i could test-out and use in my VM's and older computers (after my WBCCC-game is finished of course :lol:)? Thanks, Alex
Parent - By keoki010 (Silver) [us] Date 2011-02-25 18:53
Yes look on open-chess I'll post you a url later.
Parent - - By keoki010 (Silver) [us] Date 2011-02-25 19:52
Here you go. ust for you not a typo bad keys on keyboard.
Parent - - By TheHug (Bronze) [us] Date 2011-02-25 19:54
you can't type a ---> j

sounds like you needed a new keyboard.
Parent - - By keoki010 (Silver) [us] Date 2011-02-25 21:41
jjjjj just back from my local wally world. $20 bucks. It'll probably last a year at the most.
Parent - - By TheHug (Bronze) [us] Date 2011-02-25 21:42
Are you a little rough with them? :smile:

Edit: Did it come with a mouse? They are usually pretty cheap in a set.
Parent - - By keoki010 (Silver) [us] Date 2011-02-25 22:05
Nope no mouse.  It's the second one in 2 months. I had to replace the one on my 920 and now this one. Since I mostly use the mouse I don't understand it. Must be these cheap MicroSoft comfort curve keyboard styles. :lol: My old fingers have troubles with light strokes on the keys.  Try one of the old manual typewriters if you can, you'll see the difference. :lol::cool:
Parent - - By Banned for Life (Gold) Date 2011-02-25 22:58
Do you spill coffee on it or drool a lot? :lol:
Parent - - By keoki010 (Silver) [us] Date 2011-02-26 14:48
Neither, I think it's just the cheap membrane or whatever under the keys to make it spill proof. :lol:
Parent - By Banned for Life (Gold) Date 2011-02-26 17:43
Trust me, it's not spill-proof. I spilled some water on one of microsoft's best keyboards, and it stopped working. When I took it apart, some components seemed to be held together with water soluble glue...

Now i start to understand your experiences with the coats we talked about recently! :twisted:

Thanks George for you kind help!,

No problem, the d version is a little stronger than c but both still lose occasionally on time at 3/3.  I think it's because my TB's are on a Sata I hard drive. I might try increasing the increment or adjusting the time parameters; (don't have any idea which way to go with them though).
Parent - By SchachProfi (****) [de] Date 2011-02-25 22:22

> 3/3


Well, i thought it is best suited for analysis?!, so i can live with it losing on 3/3 occasionally... :wink:
I have collected my own test-patterns to judge the analysis-strength of an engine (for me).
For analysis you should go with the RipVanWinkle-Style... taaake your time... :grin:,
what 3/3-analysis can mean you saw in your round_1 WBCCC-game with black! :twisted:

Oh, for people not following the twin thread at OpenChess, this project has been a huge success.

This is the latest entry of the series, by Jeremy Bernstein:

http://www.open-chess.org/stockfish_pa_gtb_gran2k.7z

Has the best hash management of any engine I've ever seen, and fixes the granularity issues of Stockfish.

Enjoy.

Does this mean that someone can now set aside a reasonably fast machine and have it contemplate the starting position to depth 70 over a month or so?
Parent - By sockmonkey (***) [de] Date 2011-03-14 08:58
I was the last one to touch it, but Peter C, Martin Wyngaarden, Fruity and BB+ all provided code and/or input.

There is a git repos with the work here: https://github.com/jeremybernstein/Stockfish_PA_GTB, in case anyone wants to get involved with tweaking.

And what's the best without GTB code?  Stockfish_201_PA_K.zip ?

what means _PA_ in engine Name, or _gran2_ ?
Parent - By sockmonkey (***) [de] Date 2011-03-14 09:14 Edited 2011-03-14 09:16
PA = preserve analysis
Gran2 = the granularity is internally 2 instead of 8, resulting in an output granularity of 0.01 rather than 0.04

And just use it without the TBs, in which case the TB code won't be executed.

> And what's the best without GTB code?


There's no version that fixes granularity that doesn't use GTB code (or for people that can't deal with my negatives: all versions that fix granularity have GTB code).
Parent - By sarciness (***) [gb] Date 2011-03-15 07:22
Thanks for all the hard work, guys. Loving the new version! Thanks.
