The puzzles on his site are scrambled versions. I checked the last 10 puzzles and they were all ME to puzzles in Gordon's collection. It's just a little strange that the website does not mention this. It would have been polite to reference the source.

I checked the last 10 puzzles and they were all ME to puzzles in Gordon's collection. You are absolutely right, nearly all of them are from Gordon Royle. I now added a comment on the the index site saying so. (it might take a few minutes for the comment to show up, my internet connection is rather slow atm). Shame on me for not doing it in first place.

Thanx Ruud, I knew it, but I hoped Moritz would admit it before you cornered him Moritz wrote: nearly all of them are from Gordon Royle Unfortuantely for you Moritz, ALL known 17 clue sudokus are on Gordon's list. So you've either taken all of them from the list or you've generated some which happen to be on the list , or you've generated new ones You are on a PROGRAMMERS forum you have to be clear about this IMO, especially because most of us can look through isomorphism quite easily..... tarek Back to top Moritz Joined: 07 Oct 2006 Posts: 23 : Location: Edinburgh, Scotland Items Posted: Tue Oct 10, 2006 9:16 pm    Post subject: Hi, Moritz wrote: nearly all of them are from Gordon Royle Unfortuantely for you Moritz, ALL known 17 clue sudokus are on Gordon's list. So you've either taken all of them from the list or you've generated some which happen to be on the list , or you've generated new ones [/quote] I did generate some 17 clue sudokus, but they were on the list. However I think I can claim to have done some of the work, so the statement that nearly all of them where from the list is valid IMHO. I select my Sudokus randomly, so I don't really know how much of my daily Sudokus are my own work, and how much is from the list. BTW I contacted Mr. Royle about the license for his Sudokus, and he agreed to release them under a CC license: http://creativecommons.org/licenses/by/2.5/ I hope I clarified everything there is to clarify;-).
