Sudoku Puzzle Solver

Overview

This project is a Sudoku puzzle solver implemented in Python. The solver uses either the Backtracking algorithm or the AC-3 (Arc-Consistency 3) algorithm to find solutions to Sudoku puzzles. The graphical user interface (GUI) for the application is built using Tkinter.

Features

• Sudoku Solver Algorithms:
  • Backtracking Algorithm: A classic depth-first search algorithm for solving constraint satisfaction problems.
  • AC-3 Algorithm: An algorithm used for making a problem arc-consistent.
• GUI: A user-friendly interface built with Tkinter.
• Load Puzzle: Allows users to input Sudoku puzzles manually.
• Solve Puzzle: Automatically solves the input puzzle using the selected algorithm.
• Clear Puzzle: Clears the board for new input.

Requirements

• Python 3.x
• Tkinter (usually included with Python)
• Optionally, any additional libraries for enhanced functionality (e.g., NumPy, though it's not strictly necessary for basic functionality).

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/Sudoku.git
   cd Sudoku

2. Install required dependencies:

   Tkinter is included with Python standard libraries, but ensure you have it:

   sudo apt-get install python3-tk  # for Debian/Ubuntu
   sudo yum install python3-tkinter  # for Fedora/RedHat

3. Run the application:

   python3 sudoku.py

Usage

1. Open the application:

   Run the sudoku.py file to start the GUI.

2. Solve the puzzle:

   • Click the "Solve" button to solve the puzzle using the selected algorithm.
   • Choose between Backtracking or AC-3 from the options if available.

3. Clear the puzzle:

   • Click the "Reset" button to reset the grid for a new puzzle input.
