Apr 22, 2019 at 19:07 comment added gnasher729 @TravisWells You can obviously create a Sudoku with 16 rows, 16 columns, 16 boxes with numbers 1 to 16, 25 rows, 25 columns, 25 boxes with numbers 1 to 25 and so on.
Apr 22, 2019 at 5:16 comment added The T @Dracoins n2xn2 as in what? 9x9 grids. all of them can be solved. All this time, I was misled that it was a np-hard problem. Now, I can create more constraint algorithms. Now, comes mario.
Apr 22, 2019 at 3:34 comment added Draconis @TravisWells The sudoku problem isn't NP-hard: it can be solved in $O(1)$, as you have. The NP-hard problem is generalizing it to an $n^2 \times n^2$ grid with $n$ digits. This can be solved in exponential time with respect to $n$, and verified in polynomial time; the big question is whether it can be solved in polynomial time too.
