Hi Paquita
Great results again.
I checked that the 47 B10B puzzles have a non-degenerate tridagon, all with only one guardian.
Using the tridagon rule, 12 of them can be solved using only whips[2] and Triplets.

Hi coloin
I also checked your list of 98 (does it include Paquita's list of 47?).
All have a non-degenerate-tridagon, almost all with only one guardian (the other 4 with 2 guardians: #44, #45, #46, #47).
33 can be solved using only the tridagon rule (with one guardian), whips[2] and Triplets.

Tridagons in general as defined here: http://forum.enjoysudoku.com/the-tridagon-rule-t39859.html#p318373 and in [UMNR] or [HCCS2].
A guardian is any non-tridagon candidate in any of the 12 tridagon cells. It "guards" against the contradiction the naked trivalue oddagon pattern would imply.

Thanks i assumed that but was never sure ... but i guess for the casual reader it wasnt crystal clear

Code: Select all
1...5678....18....6..7.3....1..37.58...5..31......16.7.4.........2......86....573#45


morphed and expanded #45
Code: Select all
+-------------------+-------------------+-------------------+
| 6     9     123   | 123   8     4     | 12357 1357  2357  |
| 5     123   4     | 9     123   7     | 6     138   238   |
| 123   8     7     | 6     5     123   | 4     139   239   |
+-------------------+-------------------+-------------------+
| 123   4     9     | 1238  1236  5     | 1237  1378  23678 |

So in box 5 ... we cant immediatly insert either the 6 or 8 ... so that must be trickier

unlike the single guardians which are straight forward as in morphed #38
Code: Select all

single guardian, 7 cant go in r4c5 and has to go in r6c6

Edit...Which is a bit odd because the twin puzzles ought to have the same solving path .... hmmmm
Code: Select all

1...5678....18....6..7.3....1..37.58...5..31......16.7.4.........2......86....573#45 ***
1...5678.....8..3.6..7.31...1..37.58...5...1......16.7.4.........2......86....573#46 ***
1...5678....18..3.6..7.3....1..37.58...5...1......16.7.4.........2......86....573#47 ***
1...5678.....8..3.6..7.31...1..37.58...5..31....8.16.7.4.........2......86....57.#48
1...5678....18..3.6..7.3....1..37.58...5..31....8.16.7.4.........2......86....57.#49

So not all the minimal puzzles fromn the original expanded puzzle [ which has 9 other twins] has the same solving path / number of guardians...

single guardian, 7 cant go in r4c5 and has to go in r6c6


Right, but don't believe this is true in general. A puzzle with a single guardian can be much harder than one with many guardians (using ORk-chains).

coloin wrote:So not all the minimal puzzles fromn the original expanded puzzle [ which has 9 other twins] has the same solving path / number of guardians...

If you start from a puzzle P0, expand it into P1, and then search for all the minimals of P1, then some of them may be harder than P0. There's nothing odd here.
In the same way, some of them may have a different number of guardians.

Thanks for sorting that out ... it seems that those puzzles #44-48-dont expand as far .....
denis_berthier wrote:Right, but don't believe this is true in general. A puzzle with a single guardian can be much harder than one with many guardians (using ORk-chains)..

Is that with ? or without ? the single guardian inserted ?

In the case of the #37 case with the 7 inserted at r6c6 the difficulty is reduced somewhat

|695|...|.74|

|...|...|1..|
+---+---+---+  SE=4.2 and BxB is 0

Searching for more double guardians , if thats possible, might be a step for Paquita !!!

I mean using the tridagon pattern in both cases, i.e. inserting the single guardian in one case vs using ORk-chains in the multi-guardian case as shown in my previous post.
