I'm worried about your minimum scores in your latest rankings list. I put all the puzzles that score 0 into my solver and, disregarding whether techniques are required on different steps, I come up with these scores:

Code: Select all

 puzzle        score  techniques

#63 (ab)         3      nt,np
#19 (vidarino)   2       hp
#6  (vidarino)   2       hp
#36 (Ruud)       1       np
#22 (Ruud)       2       hp
#4  (ab/Tarek)   1       np
#30 (vidarino)   2       hp
#84 (JPF/Tarek)  2       hp

This thread started nicely, but ended causing a headache

My rankings were based on consistancy first, then difficulty second (in an attempt to insure quality of a puzzle)........

Let me take the last puzzle (JPF/Tarek).........

naked doubles were not needed if you spotted the hidden double (in column 7 or box 9)......

Now, the hidden double must have a counterpart (which is a naked triple)...which led to the fact that a the hidden subset can't be constant unless in the context of the superior the counterpart was a naked quad or higher (you can adjust that too)......

The way around this was to say that a hidden subset/naked counterpart are constant.......

In the above puzzle Hidden double/naked triple, but is it ????

Unfortunately not

The hidden double in box 9 uncovers a hidden single in the same box, which means that (in theory) somone may see the combination as a hidden triple.......

That is why on consistancy it scored a 0....

another issue.... the puzzle also can be solved using a swordfish or a jellyfish (buit that didn't go into the equation)..... also Ruud's puzzle #100 can be advanced using UR which kills many other techniques used...

Are you going to tell us what's happening with this lot first? Will they be published?

I've PM'd Papocom soon after we've reached the 100, he PM'd me back confirming receiving the 1st PM & that he would look into it soon...

That's really it

we also have 50 inferior puzzles (if you include the two 27 step non-symmetric 17s), which would surely enhance this collection

and we also have 22 low-steppers, from 1 to 8 steps, specially designed for beginners.

Indeed, that thread was mentioned as well...waiting for a reply

Is there an easy way to compile the 100 puzzles into a .sud libray book file, bear in mind that I do not have the Pappocom software.....

[Pappocom]

Just in case tarek's post causes some confusion. A SUD (.sud) file is an individual puzzle in my Sudoku program. A Library Book is a SUDBOOK (.sudbook) file. I think tarek is asking about creating a .sudbook file.

is there a description of the minimal requirements for .sud and .sudbook?
thanks

[Smart_A1ec]

nice ones you wrote those yourself?

[Pappocom]

The SUD format is closed, but the SUDBOOK format is open source. SUDBOOK is explained in (a) the Help file for my Sudoku program, under "Creating Library Books", and (b) the "template.sudbook" file which can be found in the working directory for Sudoku - that is, the directory where you have my Sudoku program installed.

yes, sure, here's an example - one puzzle per row, and <serial> will be the puzzle-number (must be in range 1-200)

i used Excel, you'll probably have an easier way.

Thanx Pat,

that was REALLY helpful.

I'm curious about how this would score/rate. It has only 20 clues (minimal), and nice symmetry. I count two hidden triples (same step though), and later an X-wing. There is also a hidden double, and possibly two naked triples. (But, as usual, I might miss the easier path).

Code: Select all

 . 1 . | . . . | . 2 .
 . . 3 | 4 . 5 | 6 . .

 . . 4 | . 5 . | 3 . .

Anyone interested in another thread, with more difficult puzzles

tarek

My generator can cope with xy wings and quads now

I'm curious about how this would score/rate.

That one's a beaut, Ocean! I'm not going to try and second guess how Tarek will score it though.

[tarek]

I'm curious about how this would score/rate.

It's a great puzzle that is a superior, however it displays little consistancy........... The hidden double & naked quads can be achived with triple & quads....

The only constant feature is the x-wing...therefore it scores a 3

Anyone interested in another thread, with more difficult puzzles

My generator can cope with xy wings and quads now

I was thinking of something which is tougher actually, fish & quads however they should be consistant even against the mights of unique rectangles,xy wings & colouring/finned xwing.....

I may be over my head with this but my feeling is that we've done enough with this superior thread......

I probably need to make some final replacements especially to #84. Also several of Ocean's puzzle are symmetrically the same & may need just a minor change to an equivelant symmetrical form...........
