Description

I have created an algorithm that generates n2*n2 Sudoku Grids and Puzzles(by removing elements) and provides their solutions without backtracking. I have managed to use a sat-solver for Sudoku Puzzles and converted my complete grid and puzzles into CNF formulas.I've tried an attempt at reducing CNF (which is np-complete) to my algorthim for 9x9 grids. The verifier says the boolean formula is correct. Due to its length I will upload it. .Here's a link to the specifics of the
algorithm.https://www.reddit.com/r/computerscience/comments/bidatb/shiftl_language_is_in_np_or_p/
