GreKo 2018.01
-------------
31-Jan-2018
(fix) * Hashtable fix: do not record score returned from unfinished iteration.
(chg) * Evaluation terms for passed pawns modified.
(chg) * Time management formula modified. Better for very short time controls.
(old) * Variable strength is back.
This version supports reduction of strength by adjustement of search speed.
You can use UCI parameter "Strength" or run GreKo with a command line parameter:
GreKo.exe -s <level>
where level is an integer number from 0 to 100:
Level Knps Rating
----------------------------
0 0.1 1600
20 1 1800
40 10 2000
60 100 2200
80 1000 2400
100 10000 2600
You can use any intermediate value for level, speed of search will be interpolated.

Re: GreKo 2018.01
Thanx Vlad! Any estimate of how stronger it is compared to 2017?

I hope at least 10-20 points. But I did not test it on long time controls.CMCanavessi wrote:Thanx Vlad! Any estimate of how stronger it is compared to 2017?

Re: GreKo 2018.01
It scores 70%(+120 Elo points) against GreKo 2017 at ultrafast time control (1 sec + 0.1 sec. increment). But I am not sure it's not because of a new time management formula.CMCanavessi wrote:Thanx Vlad! Any estimate of how stronger it is compared to 2017?

Re: GreKo 2018.01
Looking forward to testing his version. Sounds like it could be the strongest GreKo yet.

Re: GreKo 2018.01
IMHO those CB GUIs are obsolete since long, at least for serious engine testing.SzG wrote:Unfortunately Fritz 15 does not recognize the engine, name field remains empty after loading it. Even if I fill it manually it won't be installed.
GreKo 2017 behaved similarly but there at least manual filling of the name field helped.

Sorry, never test it in Fritz GUI. Even does not have it on my machine.SzG wrote:Unfortunately Fritz 15 does not recognize the engine, name field remains empty after loading it. Even if I fill it manually it won't be installed.

Arena, Winboard, cutechess-cli recognize GreKo without any problem - enough for me.

Re: GreKo 2018.01
Can you specify "-log" command line parameter for engine in Fritz GUI? GreKo will create GreKo.log file with all incoming commands, maybe this can help...SzG wrote:Unfortunately Fritz 15 does not recognize the engine, name field remains empty after loading it.
