Suppose...
1 you need brute force/backtrack
2 Start at grid 1, than 8, than 2. So the first 3 top left
3 About 2000 solutions per grid

Then the right guess is possibility #1000. The middle one.
Per grid. Then you need 1k x 1k x 1k is a billion for the 3rd grid.

So this is not the way to go.
The alternative is that you avoid brute force backtrack and test all methods. That is very slow AND you need to have all methods programmatically implemented .

I gave up after 4 hours...

The puzzles presented here until now have been either very easy or incredibly difficult. I offer here two 85-X-DOAG puzzles in the mid-range, about SE ~5. They both have rotational symmetry.

Hope they're of some interest.

Finally (being home-bound) I got my new solver in visual studio/basic 2019 up and running.
The good news: My original 85-W-doag with singles-only is solved in 1.65 seconds

.

Sadly I still cannot solve both 85-X-doags of m_b_metcalf.

Using Old SE (1.2.1.3), the 1st 85-X-DOAG is rated ED=4.4/1.2/1.2 (XYZ-Wing). The 2nd one is unrated.
Using SukakuExplainer (1.14.8), both are rated ED=5.0/1.2/1.2 (Naked Quad).

Basic Methods are Pointing Pairs/Triples, Box-line reduction and Naked/Hidden Pairs/Triples/Quads.
Besides Basic Methods are there methods used like Kite or Skyscraper that have a lesser SE than Naked Quad or XYZ-Wing?
Below is a 85-X-doag that can be solved with Basic Methods and no other methods,
that is solved in 48 seconds :shock:

I took the liberty of examining your puzzle for redundant clues, not assuming only basic techniques, and removed some of them. The (difficult) result is below. It takes my program 100s to solve. It's still not minimal.

Thanks Mike,
I will look into it. Because my last puzzle was up-down and left-right symmetrical it was surely not minimal.

A logic solver like SAT or Gurobi is still faster.

That's a very good question as my solver has failed to solve this very difficult one that requires, I think, global methods. However, I have now discovered a bug in my program and I will send you a partial solution by PM and ask you to check whether it's correct as far as it gets.

Thanks,
