Garbochess v2.20 released

[gladius]

You can get it from http://www.forwardcoding.com/projects/g ... 2-v220.zip.

New in this version:
- Fail low re-search now researches on same ply
- Better search ordering in PV nodes only now
- Removed 1.5 ply LMR
- Increased pawn shelter values
- Better null move verification

It looks to be about a 40 elo increase from v2.11.

By the time I get about 50 games from a version, you release a new version.

I've had a lot of time to work on the engine lately .

Hi Gary,

Please note that at this rate of releasing new versions you can't expect a sufficient number of games for rating lists. GC 2.02 had played only 24 games for the CCRL blitz list when 2.10 came out. I switched to 2.10 but up to now it has played only 139 games which means an error margin of 50 (!) elo in its strength.
Although I am looking forward to the progress of your promising engine, I decided to stick with version 2.10 until the margin goes down to 30, and only then will I switch to a version that is current at that time.

Hi Gabor,

whilst I can see your point and also find that a little frustrating, I don't think I'd ever try to discourage a keen engine author like Gary.
GarboChess could well be one of the giants of the future, considering the rate at which it's improving.

Regards, Graham.

I certainly understand! I basically release the engine when there has been a significant strength increase, and I think it's relatively stable/bug free. I don't expect each new version to be tested extensively, and I'm happy to see any results at all .

Hi Graham,

With the policy I have chosen regarding frequently updated engines it is not at all frustrating for me. The last thing I wanted was to discourage Gary and I hope he did not take it as such. As I myself indicated in my initial response, I can easily imagine that with GarboChess a new star has been born.

Sorry, Gabor. It is not the author's problem, it is the tester's. Authors can release any number of versions they want, testers should find _the_ way_ to deal with it. Personally I'd like to see as many versions as possible without limit. It's just me, also I suspect there are others like Harun, Tony etc who may share my view but I can't speak for them.

Silencing the other party is something that irks me

I prefer to get a new version once every 3 months or so, instead of once every weak.. Again, 100 points improvement every 3 month is better than 33 every few weeks.

I agree, Swami. But who told you I had a problem? I test what I want. Jus wanted Gary to know what he can expect (he himself referred to CCRL when he released a previous version and was asked about the strength of his engine).
