- The solver uses a series of 9x9 grids to represent the Sudoku puzzle
- Each cell is represented by binary variables (0 or 1) for each possible digit (1-9)
- Constraints are applied to ensure Sudoku rules are followed (row, column, and 3x3 box uniqueness)
- The linear programming model optimizes these constraints to find a valid solution
- Microsoft Excel (version X or higher)
- OpenSolver (An open-source Excel LP solver)
- Enabled macros for full functionality
- Download the Excel file
- Enable macros when prompted
- Install OpenSolver 2.93x and enable it in addon
- You're ready to start solving Sudoku puzzles!
