From the 2 tridagons you simply get -2r4c8 and then 6r5c9, which lowers the SER to 8.8.
(2r4c8->24r79c7->8r6c7->18r79c9->6r5c9, killing all externals of the other tridagon, and with 8r6c7 forces 6r5c9, that must be true)

Hi eleven.
Edited because I did an
I tend to post the puzzles so that the tridagon is easy to see !!!
The original new 11.9 puzzle [MJ] that I posted is on the previous page and also in the puzzles section ... here along with a trickier one [DT] as a tribute to mathimagics. They do attribute your techniques for both puzzles !!

Coloin , eleven
yes I did find that two 11.9 that you published but had not published them, that is correct. So credits for it go to you.
Yes the 11.9 that eleven talks about is another two 11.9 puzzles that I just published.
Eleven you used the expand I think to conclude it is an easy puzzle. I published the expand together with the two minimals.

Thank you coloin for keeping track of all the BxB.
I have some more again as well, I used your batch as seed, you obviously do different things than me with the puzzles so that gives me new puzzles when I use my procedures. But there may be an overlap between what we do. And I yet have to rate these.
B10B
B9B
and now I also find B8B

Re: The BxB classification of T&E(2) puzzles

.
Different search methods are used by different puzzle diggers, each leading to new original puzzles. Has anyone tried searching along the following lines (which work within a fixed set of solution grids)?
Fix some value of p (say 8 or 9 or more).
1) Consider all the known minimal puzzles with BxB ≥ p - in solution-minlex form
Take all their min-expands (only one isomorphic copy of each); we know they will all be in solution-minlex form and that they will all have their BxB ≥ p.
At this point, I think all the associated minimals with BxB ≥ p have already been found by previous searches.
2) Take all the 1-expands* of all those BxB ≥ p min-expands (again filtered so that there's only one isomorphic copy of each of them). Keep only those that still have BxB ≥ p.
Again, take the min-expands.
Again, we know they will all be in solution-minlex form and that they will all have their BxB ≥ p.
Question: have all the minimals (say with BxB ≥ p) been found?
3) Iterate step 2. Same question.
(°) a 1-expand of P is any puzzle with 1 additional clue taken from the solution grid.

Re: The BxB classification of T&E(2) puzzles

Nonminimal puzzles generated limit the number of puzzles you can properly search.
a {-1+1} doesnt change the clues within the populated boxes... so a {-2+2} is better, but mamy more nonminimals are generated..
My last puzzles were from the original database minimals, generating {-2+1} and {-1+1}
A {+1-1} keeps within the solution grid but a {-1+1} also achieves this and goes outside the grid.
The new twin puzzles generated tend to have different clues in the populated boxes.
This will give more seeds, maybe more to be found ... not many though...

Re: The BxB classification of T&E(2) puzzles

1) Consider all the known minimal puzzles with BxB ≥ p - in solution-minlex form
Take all their min-expands (only one isomorphic copy of each); we know they will all be in solution-minlex form and that they will all have their BxB ≥ p.
At this point, I think all the associated minimals with BxB ≥ p have already been found by previous searches.
2) Take all the 1-expands* of all those BxB ≥ p min-expands (again filtered so that there's only one isomorphic copy of each of them). Keep only those that still have BxB ≥ p.
Again, take the min-expands.
Again, we know they will all be in solution-minlex form and that they will all have their BxB ≥ p.
Question: have all the minimals (say with BxB ≥ p) been found?
I've done something close to what I mentioned in the above post. (There are many possible variants of such techniques.)
I fixed p = 10.
Note that all the search remains within the initial space of solution grids.
1) I started form the 1184 minimals B10B puzzles in the collection assembled by coloin here: http://forum.enjoysudoku.com/the-bxb-classification-of-t-e-2-puzzles-t41922-105.html (This is not the full known collection, but not far from it; I didn't try to add the few newly found puzzles).
There are 581 non-isomorphic expansions by Singles (BRT-expands).
If you try to find all the associated minimals, each of them may be a priori harder (due to the minimisation phase). (BRT-expansion alone can't make a puzzle simpler or harder.)
In our case, it appears that there are exactly 1184 minimal puzzles not in T&E(0) - the same ones as at the start.
Considering the search methods used for finding the original collection, this is not a big surprise.
2) After the above step, I computed all the 1-expands of the 581 non-isomorphic BRT-expands.
Note: I didn't prune the expansion phase with the condition that the expansions are in T&E(2) or that they have their BxB ≥ 10.
There are 29,049 such 1-expansions and only 28,853 up to isomorphisms (notice that there are not many isomorphisms at this point). The latter are also the non-isomorphic BRT+1-expansions of the original 1184 minimal B10B puzzles. Nothing can be said a priori of the difficulties of these puzzles.
But it appears that there are no harder minimals, there are lots of much easier puzzles and there are exactly 1184 B10B puzzles - the same ones as at the start.
Considering the search methods used for finding the original collection, it was not granted that BRT+1-expansions wouldn't lead to some harder puzzle, but it isn't very surprising either because hard puzzles it's difficult to find harder puzzles.
The B10B sub-collection of minimals in the above-mentioned coloin's collection is closed under BRT+1 expansion followed by minimisation.
* "easier" means wrt to T&E-depth and BxB classification within T&E(2).

Yes i think the expands in the list have been minimized and re-expanded and re-tested.
As twin expand puzzles minimize differently this may well be the path that has enabled more to be found.
This was performed on B6B puzzles and on on rare occaision this gave an upgraded BxB - this was probably the path taken for many of the initial finds.
I have collated the new max expands from previous posts, and will add a 2nd link for the minimal puzzles once processed.
minimizing the B10B and rexpanding did not produce any of puzzles > B10B

The minimisation phase takes much time due to its combination with the elimination of equivalent minimals.
The elimination of redundant minimals is (time and space) quadratic in the number of minimals (at least if you use gsf's software - but I think it's essentially quadratic).
One way to reduce the computation times would be to run them complete grid by complete grid: it's obvious that two minimal puzzles with different complete grids can't be isomorphic. Similarly, different minimals with different numbers of clues can't be isomorphic.
Unfortunately, AFAIK, gsf's software has no option to use this.
Considering the size of mith's TE3 database of minimals, he must have used some similar splitting; I think he talked of the number of clues.
Has anyone tried using the complete grid?

One way to reduce the computation times would be to run them complete grid by complete grid: it's obvious that two minimal puzzles with different complete grids can't be isomorphic. Similarly, different minimals with different numbers of clues can't be isomorphic.
Unfortunately, AFAIK, gsf's software has no option to use this.
Considering the size of mith's TE3 database of minimals, he must have used some similar splitting; I think he talked of the number of clues.
Has anyone tried using the complete grid?

What I am doing as "cleaning work is in this direction, but you'll dislike it, the code requires an "intel set of instructions".
If you post a small example of a file to check and what response you would like to get back, I'll see what would be my answer using my code.
I could do that in the ongoing test of the DLL to build doing the minlexing of a solution grid
