New Giraffe (Sept 8)

[matthewlai]

This one only has some small changes. No 100+ Elo jump like last time.

https://bitbucket.org/waterreaction/gir ... 150908.zip

Changes:
1) Score reporting is now scaled down by 1/10. Hopefully that will play better with score-based adjudication systems. Score magnitudes are now more inline with what other engines report, though it's still probabilistic.
2) Time management has been improved (thanks to Graham Banks' testing that led me to notice this). About 33 Elo gained.
3) Gaviota tablebases now supported. See https://bitbucket.org/waterreaction/giraffe for details. I want to switch to a neural-network based endgame system later, but EGTB will do for now.

By the way, Giraffe is now open source, and the thesis is now available online. See thread on the programming forum if interested - http://talkchess.com/forum/viewtopic.ph ... 136#640136

This is probably going to be the last Giraffe release for a while. I have just submitted and defended my thesis. I think my brain needs a break from working on Giraffe full time for 3 months.

Will be travelling for a few weeks before getting back to Giraffe.

Thanks

Thanks so much. I love your new approach and the unique chess that your neural net plays!

Don't let the Giraffe die!

If you are trying to do Giraffe UCI and your machine is 32-bit, you have to edit Wb2Uci.eng, and make it refer to the 32-bit version instead.
