Doggo Experiment #4
(Published on 2. May 2023, 02:45 by waffles_the_dog)
Experimenting with the extreme negative constraints, this feels like it's actually quite easy (1/5), though i did struggle to remember disjoint set restrictions, even while setting.

Rules are as follows:
- Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.
- Digits must not repeat at corresponding box positions. (Disjoin set)
- Digits must not repeat in cells that are a chess king's move apart.
- Digits must not repeat in cells that are a chess knight's move apart.
- Orthogonally adjacent cells must not contain consecutive digits.

Solution code: The digits from column 1, in order, from top to bottom, and the digits along row 9 from left to right, with no spaces or punctuation

Added a note on the disjoint set constraint being unnecessary, removed the tag for such.
I assume I broke the requirement for disjoint sets while trying to ensure a non-bifurcation path existed.
