Antiknight Thermo Sudoku
(Published on 22. July 2020, 22:40 by dgreenspan)
Normal sudoku rules apply. Digits on a thermometer must be strictly increasing starting from the bulb. Cells that are a chess knight's move apart must contain different digits.
Solution code: column 1 and row 9

More of a 3.5 star to me, though I am very familiar with these types of puzzles, so I might be a poor judge of difficulty. Took me 18:59.

After two evenings of not seeing the start, I used heavy T&E to crack it. Without the comments, I would not have been sure, if that puzzle is logically solvable. After solving it the hard way, I asked a fellow puzzle friend, who gave me a hint. Now I agree that the start is really nice but also really hard to spot. I suggest to give a hint in a hidden comment for all the people like me. That might also give some of the solvers a reason to reevaluate their rating.

@HalfBakedLunatic In the end I used it to test the computer solver I've been writing, and it solved it with one solution.

@pdabraham - yeah, me too. I can put all the possible combinations into the thermos but I'm stuck at that point.

Couldn't work out where to start.

@Ragna Both are strictly increasing.
Sometimes mathematicians call the sequence 1,2,5,5,6,8,8,13 "increasing" (which allows some terms to be equal) but 1,2,3,5,8,13 "strictly increasing" (none are equal)

Sorry. What does the definition of "strictly increasing" mean?
12345.. or 13457..?
