INGAR'S SUDOKU SOLVER
I'm not a fervent sudoku solver but I always wanted to try implementing
a program to solve the puzzles faster than I can. This is my first attempt.
This program uses the Qt library for its user interface, you will need
to have it installed to run the program.
BUILDING INSTRUCTIONS
Basic building instructions
mkdir build
cd build
../configure
make
The binary will be called 'sudoku' and be located in the 'src' directory.
USAGE
Running the program will show the main window, which consists of a basic
sudoku grid (9x9) and a number of buttons.
The SAVE button allows you to save the current sudoku puzzle to a file,
like wise, the LOAD button allwos you to load a previously saved sudoko.
The file format is extremely simple: the files can be opened and edited
with a text editor. Note that empty (unsolved) positions are saved as well.
The CLEAR button will clear any previously entered numbers.
The STEP button can be used to solve the puzzle. If clicked, the program
will verify each empty cell. If a unique solution can be found for a cell,
it will be added to the solution. You will probably need to click STEP
several times to completely solve a puzzle.
LIMITATIONS
The current solving algorithm will only find a complete solution as long
as there are cells for which a unique solution through elimination can be found.
It cannot perform an exhautive search if the sudoko contains only cells for
which at least 2 solutions can be found.
