testing killer sudokus

Hello,

I have updated my software that generates "Calcudoku" puzzles to also create Killer Sudokus. The program isn't quite there yet: especially the difficulty rating is off, I think.

Opinions from Killer Sudoku experts will be much appreciated.

thanks,

Patrick

The PuzzleMix discussion area is solely for discussion of the PuzzleMix puzzles and site. I have removed the link.

There are many general-purpose puzzle discussion forums elsewhere.

Ok, I understand that this is the policy of the site, no problem.

On another note: I sent you e-mail about Calcudoku puzzles (July last year,
and about two weeks ago), would it be possible to reply? Are you interested
in some kind of collaboration?

thanks,

Patrick

Hi,
Sorry, I already make Calcudoku puzzles and have been publishing them for many years (albeit not on PuzzleMix to date).

I have had over 35 books published, including by most of the world's top publishers, and many of these contain Calcudoku. They're also in most issues of most of my magazines for the past few years.

Just to say further, I have a policy of never acquiring puzzle content from other authors (except for my puzzle fanzine Sudoku Xtra). I make puzzles as my full time job, and much of the pleasure for me is the challenge of creating them in the first place. Also there are many issues (in general) to do with consistent formatting and also checking.

Hi Gareth,
Your puzzles are in general MUCH more interesting than Patrick's. He has a few cute ideas, including some that are much more enjoyable done online than on paper.

One thing that he's developed for his calcudoku is the system of difficulty ratings. I think they're pretty amazingly good for an automated system.

hi Gareth,

ok, thanks for the explanation, I understand.

As you may have gathered, this is not my full time job, I'm doing my site as a hobby
(which explains why my puzzles are not created by hand..).

I'm curious: how do you ensure a Calcudoku has a unique solution?

Patrick
