New Giraffe (Sept 8)

[hgm]

No box to check in the Fritz gui running the engine as winboard to uci

Well, if the Fritz GUI does not support switching on and off pondering of engines that support pondering, perhaps you should considering using a more capable GUI.

Hello GENERALISSIMO !

Giraffe works very well ! But....not in Windows XP ! It wasn't compiled for this OS !

Very interesting article. Thanks for posting the link.

That looks to be a bit of a stretch to me. "at the level of top programs"? "at the level of IM"? First, those are contradictory terms. Second, I am not sure it is an IM yet, at least watching on ICC recently.

International Master (IM)
"International Masters" redirects here. For the snooker tournament formerly known under this name, see British Open (snooker).

The title International Master is awarded to strong chess players. Instituted in 1950, it is a lifetime title, usually abbreviated as IM in chess literature.

Normally three norms in international tournaments involving other IMs and Grandmasters are required before FIDE will confer the title on a player. IMs usually have an Elo rating between 2400 and 2500. Sometimes, though, there may be an IM who has not yet become a Grandmaster but has a rating greater than 2500.

The IM title can also be awarded for a few specific performances. For example, under current rules, the runner up at the World Junior Championship will be awarded the IM title if he or she does not already have it. Current regulations may be found in the FIDE handbook.[6]

After becoming an IM, most professional players set their next goal as becoming a Grandmaster. It is also possible to become a Grandmaster without ever having been an International Master. Larry Christiansen of the United States (1977), Wang Hao of China, Anish Giri of The Netherlands, and former World Champion Vladimir Kramnik of Russia all became Grandmasters without ever having been an IM. Bobby Fischer of the United States attained both titles solely by virtue of qualifying for the 1958 Interzonal (IM title) and 1959 Candidates Tournament (GM title) entirely bypassing the usual process of achieving norms at each level only incidentally becoming IM before GM. However, the more usual path is first to become an IM, then move on to the GM level.

An International Master is usually in the top 0.25% of all tournament players at the time he or she receives the title.[7] The November 2010 FIDE rating list records 3036 players holding the IM title.[5]

No matter how you look at it, this is a very interesting project.
There are not many serious attempts to do chess evaluation based on learning and most attempts are not terribly successful.

From CCRL 40/4:
211‑212 Giraffe 20150828 64-bit 2307 +38 −38 46.6% +25.3 19.1% 251

not quite as good when playing faster games.

And CCRL is deflated there (in the lower range) compared to FIDE ratings. Most probably exactly FIDE 2400-2500 level of an IM.

In my paper I only claimed that the evaluation function is at the level of top programs, which I believe is substantiated, given that it scores about the same as Crafty on the STS, searching less than 1/10 as many nodes (and much higher with time odds so that it searches as many nodes).

It scores higher than Texel, at equal time (searching about 1/4 as many nodes).

I think they mis-interpreted it to cover the whole program.

The article was written without my input at all. I actually didn't find out about it until a few hours ago.

With teaches itself I think about unsupervised learning. But it is not.

Neural networks are not much fun for you start the tuner and sit and wait.
Quite boring or not ? I don't like tuning at all.

But I would like to know the limits of this neural network approach. How long do you have to wait before it has ELO > 3000 ? Maybe someone allows you to use a fast cluster.

You also don't know if you have chosen the right feature representation. Or not ?
