PostForum: Releases   Posted: Thu Jan 03, 2008 7:09 pm   Subject: Sue de Coq, v 3.1.0.1
Ruud,

Sudocue version 3.1.0.1 seems to detect most Sue de Coq patterns (it's found several which I've missed), but I've found a few which it doesn't. I've slowly began undertaking some of the so-c ...

I guess the only remaining loose end for me regards your original mutant Jellyfish. It would appear that the base set (r2r3c2c5) for that pattern has houses with common candidates: r3, c2 and c5 sh ...

Sudtyro,

I'm sorry, I can't really help with your questions. The thread I referenced was basically a "learn as you go" experience for me so I don't want to claim any expertise in this ar ...

I've not yet tried the latest Sudocue release (3.1.0.0). In version 3.0.0.3, there seems to be a problem with "Sue de Coq" pattern recognition. As an example, for the 5 May 2007 Nightmare, ...

Really learning a lot on this thread...

A general question: When there exists a single digit AIC loop (sometimes called a "fishy cycle", and I'm beginning to see why), is there always an associated fish structure, as in this puzz ...

rep'nA, your method is the answer that I couldn't find but I do still wonder whether it would matter if r2c12 were "givens" rather than "solves"?

zoltag,

For the grid that you show, I like Jean-Christophe's "closed loop" idea in his post. I would use "AIC loop" or maybe "AIC ring," but of course the name isn't ...

Para,

Very nice. Your AIC to eliminate (2)r9c9 is correct, and it's not really an easy one to start with.

I agree that your argument to eliminate (8)r4c9 is more natural than the almost XYZ win ...

Sudtyro,

Perhaps the way I presented things suggested that I determined a priori to consider only two of the possible swordfish eliminations and disregard the others. This was actually after the f ...

repn'A,

Your simpler alternative is a nice observation. Thanks for pointing it out.
