sudoku Move unit tests into sudoku module to get rid of export_all Feb 5, 2013


This is an Erlang version of a sudoku solver, mostly based on the
solution by Peter Norvig.
For comparison, see my slightly modified version of Norvig's Python code:

To try it out, simply compile and run the sudoku script:
$ ./rebar compile
$ ./sudoku

The solution for file.txt will be saved as file.out in your current directory.

You will need to have Erlang installed with escript in your path.

To only run the tests:
$ ./sudoku runtests

To solve the sample files without running tests:
$ ./sudoku solve

To solve a specific file (e.g. hardest.txt):
$ ./sudoku solve hardest.txt
