Stockfish & Table/Bit bases

[alpha123]

Is there any chance of Stockfish supporting tablebases/bitbases in the future? I know Nalimov TBs are impossible because of the license, but could Gaviota TBs be used? Or Scorpio EGBBs (which I am pretty sure the probing code for those is GPL, so that shouldn't be a problem legally).
Maybe even RobboTripleBases and/or RobboTotalBases, though I don't think there is a library for probing those .

Just curious,
Peter

Yes, it is possible to plug the gaviota TBs and the authors showed some interest when there was a discussion a couple of months ago. There is no license problems at all with them. I have not heard anything and I have not seen Marco lately in the forum, but I assume they will try to connect the TBs at one point. If they decide not to connect the TBs to Stockfish, I may connect Stockfish to the TBs . Both are free and open source. However, I prefer they do that. I really do not like spending time learning the internal details of another engine. It will be much easier for them.

PS: I am interested to know how the TBs will perform in a fast top program.

Or if you don't, I might .

Thanks for the license info, I will definitely use them (the GTBs) in my engine. (Which will be under the GPL, once I actually finish it.... )

I hope Stockfish gets TBs and possibly BBs, then it will be an even better analysis engine. It will also be interesting, like you said, to see how well GTBs work in a top program. Probably no different than in Gaviota .

Thanks,
Peter

Hi Miguel,

yes I was interested and still I am, but unfortunatly in this period I have very very little time and I am not sure when I will take a better look at your TB.

But one thing is sure, at least for me, Nalimov TBs are a no-option due to licence and also because author is not actively involved in development anymore and this is a _very_ important point: unmaintained code is almost useless. Your implementation is the preferred choice....it is just a question to find some time....of course if someone wants to do the job he is more then welcomed

i would be happy, when one version of stockfish would support scorpio bitbases.
i dont know the disadvantage of bitbases.
