Scorpio 1.7 bug?

[GenoM]

hi all

Had anyone experienced such sort of problem with Scorpio 1.7?
in the game against Crafty from 46th move it began to use only 2-3 seconds/move and of course lost the game

thanks George

i think i was using Scorpio 1.7X but i am not so sure now...
the matter is that i am using a new PC and my previous hard disks are temporarily unaccessible so i cant see which version of Scorpio i am using now. Only i can tell the scorpio.exe date is 21.2.2006. Is that a Scorpio 1.7X?

can you e-mail me the 1.7X version?

regards,
Geno

Ps:
indeed my scorpio.ini is the same as yours, but i dont know what 'mt=2' means... is 'mt' for MultiTreading? Cause i was thinkin that is for some sort of 'tables' - 'ht'='HashTables', 'pt'='pawnTables' and so on...

Hi Geno,

Why not using a newer version like 1.8(already 5 weeks old)?
There are also newer egbb+dll available since June.
(BTW yes 21.02.06 was the first 1.7 version released)

Yes 'mt' stands for the number of cpus used.

Best regards,
Guenther

[GenoM]

thanks Guenther

i am using Scorpio 1.8 too (yes, it looks stronger than 1.7) but i had to try by myself 'who is who':-) Because of this bug (or because of the bad influence of 'mt=2' in the .ini file) i havent tested much 1.7 version.

regards,
Geno

Hello everyone. I just noticed the same bug (feature?) in Scorpio 1.8. My scorpio.ini:

Code: Select all

Two games where this happened:

At some point Scorpio started to use 0 seconds and depth 1 for each move, making random moves. I noticed that it happens only when Scorpio is losing. Is it affected by "resign" parameter in scorpio.ini?

[Daniel Shawul]

Kirill,
Are you using the bug fixed version of scorpio 1.8?
I guess I fixed the time control bug related to incremental type clocks. I thought it never happens in standard x moves/ y minutes
tc. I will see what i can do
regards,
Daniel

[Kirill Kryukov]

Hi Daniel! Thanks for looking into this! I downloaded Scorpio 1.8 from WBEC. It does not say if it is fixed version or not. readme.txt does not mention it too. Why don't you increment the version every time you fix something? For example you could name it "Scorpio 1.8.01" if the fix was minor, or something. Then you will always know what version was used. Just a suggestion.

About this problem - Graham told me that it is Scorpio's way to resign. I saw that it happens only when Scorpio is already losing. That's why I am curious if "resign" parameter in srorpio.ini has anything to do with it. Has it? If so, it would be very nice if it was described in the "readme.txt".

I enjoy running Scorpio actually. It has interesting play and strong endgame (probably because of 4-piece bitbases). I am looking forward for the day when 5-piece bitbases will be available for Scorpio. I expect it to become stronger with them.

My wishes for Scorpio: 1. UCI support. 2. 5-men bitbases. 3. 6-men bitbases. 4. Beat Rybka, outsell Fritz.

Best,
Kirill

Hi Kirilli

Sorry about that, I will do that in the future.
Scoripio sometimes uses excessive time when it is down by at least a pawn , this may sometimes cause a problem when it is so little time left. But i never taught it could be down to a 1ply search.

Thanks for testing. 5 piece bitbases are 340mb, which i think is still too big. May be after i decrease the size a bit, i will make it publicly available.

Sorry i can't fulfill all your wishes in the near future If i ever do 6-men, they will probably will not fit in RAM and it will not be as efficient. So i do not plan to generate 6 men for now.
Well about beating Rybka... you never know, i could find the majic formula one day

Scorpio had plenty of time in my examples, about an hour or so. So the reason is not lack of time. As I said, Graham told me that Scorpio does this when it is losing, as a form of resignation. Is it correct? If so, is there way to switch this off?

Welcome! I would be happy with 340 MB, and probably many others. Four of my test machines have at least 1 GB RAM. But I respect your decision. Release it when you feel it's ready.

As you know 5-men Nalimov tablebases are about 7.5 GB, and don't fit into RAM usually. This does not stop people from using them. 6-men Nalimov tablebases are over 1 TB and people still use them, including myself. 6-men bitbases will be much smaller, and also there is no need to keep all of them in RAM. Some caching solution can be used.

Right now there is no engine that is using 6-men bitbases, so if you do it you may be the first. BTW, if you need help with generation or with distribution, I will be glad to help. If there are some practical obstacles, like computation time, I am sure that many will offer help. This forum is one good place to discuss everything EGTB-related. Especially if you will need to organize the online distribution.

Best regards,
Kirill
