As the project of improving Sukaku and sudoku explainer is active with a fresh mini release:
https://github.com/SudokuMonster/SukakuExplainer/releases/tag/v1.2.1.5

You can now paste the pencilmark grid at that stage of your solution into SE and "Get next hint"!

I will be looking at the GUI improvements too. Generated puzzles have only very few categories with the most difficult being:

Code: Select all

Hard 1.6-2.5
Fiendish 2.6 -6.0
diabolical 6.1-10.0


This should be easily customizable to new categories and ratings to be added in the drop down menu for the end-user to choose from

Any suggestions? (I was thinking of Superior & Superior+ puzzle range but you may also suggest something like 7.2 -8.0 for example)

The manipulation of this proved easy.

Tested a few interesting additional categories which could be of interest to some in a future release of Sukaku Explainer

Code: Select all

Superior (3.2 - 4.0): The idea is to require Triple(s) and/or X-wing(s) to solve
Superior+ (4.5 - 6.0): Skips Swordfish, XY-Wing and XYZ-Wing.
 Will require any of the techniques in the 4.5 - 6.0 range but
 may also require lesser echinques
AdvancedPalyer (7.0 - 8.0): Will require chains to solve

Superior (3.2 - 4.0):
require Triple or X-wing

• some 2.5 may also qualify!
• skip Swordfish

That is correct but I’m trying to work around the current awkward SE rating system without changing much. Ranking the hidden triple for instance higher than a swordfish is unfortunate!

There are solutions that involve changing the Resolution rule hierarchy and ratings but that could be a step too far for SE fans!

[tarek]

I managed to find a workaround by specifying certain ratings to be included, excluded or not maximum rating. Superior would have swordfish excluded and hidden pair can’t be the maximum rating!

Superior

and hidden pair can’t be the maximum rating!

i should've said it more clearly --
some 2.5-3.0 may also qualify

[tarek]

Yes but with the current SE setup that is the best I can do. So currently, it will produce a puzzle with a rating between 3.2 and 4.0
It will not have a swordfish nor will the maximum rating be 3.4

The options available are:

Code: Select all

category name
Minimum difficulty
Maximum difficulty
Specific technique difficulty that must be included x3
Specific technique difficulty that must be excluded x3
Specific technique difficulty that can’t be Maximum difficulty x3

cute trick


disable 2.5 (to solve the 2.5-3.0 issue)
as you disabled 3.8 (to solve the 3.8-4.0 issue)

remaining issues (which cannot be handled by this trick) --

• some 3.2 should be rejected
• some 3.4 should be accepted

[tarek]

with direct hidden triple upgraded to 3.1 and naked double demoted to 3.0 , I've got superior now as a single range 3.1-3.8

you probably mean,
Hidden Pair demoted (from 3.4)

and the range is
3.1-4.0
( if you've disabled Swordfish )

[tarek]

Thanks Pat,

Yes that was mistake.

The experimental rating changes are as follows:

Code: Select all

1.6: Naked single//2.3 ---> 1.6
1.7: Direct Pointing
1.9: Direct Claiming
2.0: Direct Hidden Pair
2.6: Pointing
2.8: Claiming
2.9: Hidden pair//3.4 ---> 2.9
3.0: Naked pair//3.0 ---> 3.1 ---> 3.0
3.1: Direct Hidden Triplet//2.5 ---> 3.0 ---> 3.1   
3.2: X-Wing
3.6, 3.8, 4.0: Naked triplet, Hidden triplet, Swordfish//3.8 ---> 4.0 4.0 ---> 3.8
4.2, 4.4: XY-Wing, XYZ-Wing
4.5 - 5.0: Unique Rectangles and Loops
5.0, 5.2, 5.4: Naked quad, Hidden quad, Jellyfish//5.2 ---> 5.4 5.4 ---> 5.2

I tried to keep track of what changes I made at the end of each line, hence the confusion
I promoted the Naked Pair then demoted it again.
Anyway,
with superior techniques from 3.1-3.8 only minimum difficulty and maximum difficulty are now needed.

[Pat]

right, swapping 3.8 with 4.0 solves the Swordfish issue.

( my comment about disabling Swordfish
was in the context of earlier discussion,
where the ratings were still fixed )

[tarek]

I can control category now using:
The options available are:

Code: Select all

category name
Minimum difficulty
Maximum difficulty
Specific technique difficulty that must be included x3
Specific technique difficulty that must be excluded x3
Specific technique difficulty that can’t be Maximum difficulty x3
Specific technique name that must be included x3
Specific technique name that must be excluded x3
Specific technique name that can’t be Maximum difficulty technique x3
