- Enhanced solver and added tests for previously unsolvable puzzles:
- 2 examples by Jean-Pierre Vidal
- 6x6 puzzles, example from Brian Helterline
- 16x16 puzzle from sudokusolver.com
- 15x15 puzzle from sudoku.com's sud.exe
- Several "evil" puzzles from WebSudoku
- Allows \%config to be passed in, thanks to Brian Helterline
- Added board validation
- Bugs fixed:
_get_or_set_square:
Worked for squares but not rectangles.
1. Had $x and $y reversed in accessing $self->{board}
2. Was using $v_squares instead of $h_squares
_array_to_text:
3. Wasn't using a copy of $self->{board}, so printing
a solution for debugging purposes screwed up later
processing.
_retry:
4. Wasn't correctly copying and restoring $self->{board},
so it wasn't able to brute force the solution to some
hard problems.
