This is a visualisation project that shows every step of a sudoku backtracking algorithm in "real time" (i.e. slowed down so you can see each iteration). This project does not aim to produce a fast or efficient sudoku solver; some sudokus can take several seconds to solve using the "skip to end" (≫) button. The project was inspired by this image on the "Sudoku solving algorithms" Wikipedia page.
To use, start an HTTP server in the repository directory then access the webpage using the browser. To do this in Python, you can type python3 -m http.server on the command line then go to http://localhost:8000/.
- Input your own sudoku or use a random pre-generated sudoku.
- Change the speed of iteration, pause, or skip to the end to see the solution.
- Change which sudoku cells the bruteforcer inputs first: rows first, columns first, or cells with the least possibilities first.
- Get a link to the sudoku you have input to save or share.
Tests are stored in the tests/ directory and are performed inside the browser using Mocha as the test framework with Chai as an assertion library.
To test, navigate to the tests/ subdirectory in your browser (e.g. http://localhost:8000/tests/).
- Add ability to solve "X-type" and "Window-type" sudokus.
