Sudoku generator and solver.
Originally developed for desktop MATLAB r2018a, tested successfully on current build of matlab web editor (https://matlab.mathworks.com/).
Any feedback and/or contributions are welcome.
TO DO LIST:
- Add validation check for solutions prior to saving, (currently, invalid solutions that reach backtracking limit as saved).
- Fix helper functions.
Release notes:
- Current implementation is a prototype, significant optimization is still required.
- All functions are self-contained within the 'sudokuSinglePage.m' program.
- Debug logging in command window for progress of each step.
- Logic is brute force generation of 9 grid squares, starting form top left.
- Each grid has a unique series of numbers 1 to 9.
- Program will attempt to solve in a linear fashion starting from top left.
- Program will backtrack to previous grids if no valid solutions are found.
- If backtrack limit is exceeded, program will exit.
- New valid solutions are added to the solutions csv file.
- CSV file is cloned prior to adding new solutions.
