Looks like a new version of Crazy Stone (known in Japan as "saikyou no igo" = "the strongest Go") will be released for PC on Nov 16th.

A very strong engine that makes human-like moves should be interesting. I hope there will be an iOS version as well.

Although https://www.4gamer.net/games/437/G043722/20181011081/ says "人間の棋譜を使用せずに，自己対戦のみで九段の強さに到達した", so this means no human games were used. But it also says that it makes human-like moves and that it has a win rate of 95% against the previous version. We'll see.

Hi Marcel,That'd be nice.Very roughly speaking, is it fair to say it's at least 1-stone better than the previous version ?
( Curious about its winrate giving 2 stones to the previous version. )

Probably more.

At dan ranks 100 ELO is about one rank, and 95% win rate is around 350(?) so it should be three to four stones stronger.

All the values are rough, someone with more love for math than me might give you a more accurate answer.

95% winrate between similar programs A and B is not the same as 95% winrate between program A and a human with the same Elo rank as program B.

Denniss Hassabis said Alphago performs better against weaker versions of itself than it does against weaker humans. It's likely the same for all AI.

The self play trap?

I imagine that this could be true of people, if we could freeze someone's play and have them play against themselves. A significant part of what you learn is identifying your own bad patterns. It just might be the case that AI is more predictable (and learns primarily through self-play) so it is even better at exploiting its past selves' weaknesses.

Well, with self play, that's what it is trained to do. Perhaps diminishing returns kick in, in terms of points. That is, even with the same win rate difference, the wins get smaller and smaller. But against other players with different strengths and vulnerabilities, at some point those small refinements do not produce the same win rate differences.

Unfortunately there is no information if a GPU is supported, only CPU requirements are mentioned.

But I don't think developers would use others engines to showcase the strength of their own.



There may be some human examples .

If a lone NN network is a hundred percent savant and zero percent seer, couldn't that both either pronounce or diminish the effect of doing well in self-play? I'm sure search balances things out, but not quite so much that pure bots can spot ladders .

Who do I have to kill for a version for linux?

There is a version for android.

Very cool, but for those with no money you can use leela master by pangafu for more human-like moves in a bot. Just use it with sabaki or lizzie as you would another weight like 40 block or elf. The most recent weights from 15 block G series (which is what you should get) has 70% human weights if I understand correctly, and I'd say it is at least on par with LZ 157 if not stronger.

Crazy Stone Zero ON SALE

Has anyone bought it and tried it, yet? Can new Crazy Zero precisely count difference in points?

Would the new version be released on steam or something?

The jp Amazon doesn’t deliver overseas right

They do for books. For other things I've used tenso as a reshipper. For crazystone, I've just used download from the company's web page, and it worked fine.

Can you explain a bit more, please? Like, is there an english version of Crazy Stone Zero, does it understand ladders (that Elf can't understand), can it count points? Examples from real games in these 3 areas would be a huge thank you. I'd like to buy if all of these prove as a positive. Especially ladders and teritory counting. Thanks!

You should probably ask the author by mail, or post your questions at computer-go.org, he often posts there.
