I'm claiming that tsumego are fundamentally harder than NP, since setups involving L&D of a big group are a common way to set up hardness proofs about go, and since eg. reading ladders is PSPACE-complete, and most people believe NP < PSPACE.

For example, ladders are PSACE-complete: http://homepages.cwi.nl/~tromp/lad.ps
Go is PSPACE-hard: http://www.levreyzin.com/presentations/Go.pdf

Go in general with Japanese rules is EXPTIME-complete, but I don't know if that result depends on evaluating potential nonlocal ko threats, in which case one could argue that is outside the scope of tsumego, which is why I'm only sure about PSPACE-hardness.

I just got an email from S&S and it was a box of 30 copies and they only have 3 copies left at this moment. Will be gone in a jiffy.

Yes, and ten of ’em are on their way to Germany, one of ’em is for me <happy dance> my heirs will be happy: these test prints are almost as rare as the red and blue Mauritius “Post Office” stamps ;-)

Hello,

I don't get why Slate & Shell don't make pdf sales, if they're not willing to reprint ? They can borrow a scanner and make a living from licence fees selling bits.

Smartgo is a good idea, but looks like their soft is both very limited (no desktop or android version, Windows is crap anyway) and the no pdf export function reminds me of the attempts of CD and DVD copyrighters who didn't get that far. Considering go as quite a limited market is the only thing that keep their library from pirates.

[admin] reference to pirated copies removed -JB [/admin]

Thanks

Just a few points:
- PDF doesn’t take advantage of the electronic medium, and is a poor replacement for a printed book. On the other hand, Go Books by SmartGo lets you resize text, replay diagrams, and copy diagrams as SGF, for instance.
- Kiseido is offering some books as PDF (http://www.kiseidodigital.com/kdb.html); they’re offering many more books through Go Books.
- Mac version of Go Books is in early beta; Android version is planned. More info at http://gobooks.com/platforms.html. (You can follow @gobooks on Twitter for future announcements.)

Hello,
thanks for your answer.

I already answered your first point by stating that "Smartgo is a good idea" in my previous post.

To your second point, Kiseido's pdf offer is limited to 4 books (and go world archives) and I was talking about Slate & Shell. The fact is ebooks format is a mess actually, and even though pdf "is a poor replacement for a printed book" (which I find dubious, owning myself quite a lot of pdf ebooks I bought, I never had an issue reading them, but I agree, I prefer PostScript) I still find it a better alternative to "yep we sell stuff that you can only read from within OUR software" (I'm not targeting you, I find Amazon, Apple & the likes approches even worse either).

About the third one, isn't the Mac version a beta for like a year for about the SAME code ? About Android, I planned a lot of stuff too that I never did, but that's just me, I hope you will achieve it eventually.

Best regards

Kiseido uses ClickandBuy for pdf sales. (Why not Mastercard/Visa or Paypal?) After authorizing payment through my bank, which ClickandBuy confirmed by email, I never received the so-called test charge from the company. (This is reminiscent of descriptions of how off-shore poker sites operate.) Do not just take my word at face value. Do a Google search for "clickandbuy scam." Or start with this "F" rating from the U.S. Better Business Bureau: http://www.bbb.org/new-york-city/busine ... -ny-94189/

I, for one, would love to purchase Go Books for Android devices! (Just not through ClickandBuy!) Are differences among various manufacturer's hardware/OS a problem or is it more to do with concerns over piracy?

My point was simply that a Go publisher has tried PDF; if it had been a big success for them, they would likely have expanded that.

No, it's the Windows version that has been in beta for a while. Sorry for the delay; I want to make sure a purchase of the desktop version can cover both Mac and Windows. Go Books for Mac has only been in beta since end of July, 2014.

Fast forward to near late 2018 and when you compare the $35 with the current Amazon marketplace price of over $450 for a regular copy, the buyers of the beta copy have had gotten a heck of a good deal.

Would be nice if it were available at 26 euros at that store but they are out of stock and the book has been long out of print.
