A simple project I started for fun and to get extra practice at translating imperative algorithms to a more declarative functional style. Right now it is command line only. I may add an interactive web front end later.
Download the sudoku.jar and board.edn file from the Releases. Update the board in the board.edn file if needed and run the program via:
$ java -jar sudoku.jar
Assuming you have clojure (1.10.1) installed, you can use the following commands.
Run the project directly:
$ clojure -M -m musab.sudoku
Run the project's tests (they'll fail until you edit them):
$ clojure -M:test:runner
Build an uberjar:
$ clojure -M:uberjar
Run that uberjar:
$ java -jar sudoku.jar
By default the board.edn file has a board state added under the input key. Apparently this particular puzzle is the hardest you can find. On my 8 core 16 thread machine it takes ~ 60 seconds, however the runtime depends on the complexty of the puzzle.
Follow the format of the example 2D array/vector for board.edn for any custom boards you enter
