Re: extreme 229

Hallo Klaus,

in extreme #229 ist H5=8 gegeben. Das fehlt in deinem Bild.

Schöne Grüße,
Klaus

Re: Discussion to One More #290 (regarding symmetries in str

Thanks hone, i think i finally understand what you have done and meant. but i'm still not sure how much sense it makes to examine a grid, from which is known that there are multiple solutions, by using UR-elimination, which is only valid if the grid has a unique solution. it seems to me you have cre...

Re: Discussion to One More #290 (regarding symmetries in str

Hi hone, i dont exactly understand what you mean. for extremes you can clearly assume a unique solution as given. when you talk about ommiting clues, here the black 2, then this new variation clearly has at least one solution (the original one will still hold here) , but that this is still the only ...

Re: Discussion to One More #290 (regarding symmetries in str

Hi hone, of course you only can use UR-arguments when its safe that there is only one solution, thats the basis of UR-arguments. we here discussed the grid alone, without any clues, where its clear that there is no unique solution. so UR based elimination is not valid. creating a puzzle UR's are of ...

Re: Bitte um Hilfe bei Extreme aus SZ Edition

Hallo Doblmosl,

in der Tat, für ein SZ-Rätsel ungewöhnlich schwer.

7 ist Pflicht in A12, d.h. GJ1 hoch ist nicht möglich. Ich denke damit kommt man weiter.

Grüße, Klaus

Re: Discussion to One More #290 (regarding symmetries in str

Hi CL, i dont know of any other 1-hint puzzle. i've been wondering for a while whats the minimum number of hints and still get an interesting puzzle. indeed before seeing Ulrichs pattern of #14, and playing a bit around with it, my bet would have been something like 3, maybe 2. but 1, i was a bit su...

Re: Discussion to One More #290 (regarding symmetries in str

Hi CL, great post. unfortunately my geometrical vision is rather poor, so i have some trouble to see all the symmetry. but i can tell what my solver thinks about this special grid. the black cells alone, without any numerical hint, reduce the possibilities this way: Str8t_290.png here e.g. F7=1, F7=...
