Generating Sudokus is a fond area of computing for me. Great job; the website is very thorough and readable. Many years ago I wrote a Sudoku generator in C++ that was based on Knuth’s “dancing links” algorithm. It then analyzed the generated puzzle in terms of what techniques were necessary to solve it, and ranked them accordingly. Perhaps there is still something useful in there: https://github.com/stlab/adobe_source_libraries/tree/main/test/sudoku https://github.com/stlab/adobe_source_libraries/tree/main/te...
