jaiswalchitransh/CSP-Map-coloring-using-Backtracking

The code uses backtracking to solve the Constraint Satisfaction Problem (CSP) of map coloring. It checks if assigning colors to regions follows the constraint that no adjacent regions have the same color. The skills involved include algorithm design for backtracking, recursion, and solving CSP problems. The implementation uses Python.

Project Overview

The Python code tackles the map coloring problem, a classic graph theory challenge where the objective is to color the regions of a map in such a way that no two adjacent regions share the same color. The code employs a backtracking algorithm, which systematically explores different color assignments until a valid solution is discovered or all possibilities have been exhausted.

Installation

This project requires Python 3.12.1 or later. To set up the project:

1. Ensure Python 3.12.1 or a later version is installed on your system. You can download Python from python.org.

2. Clone or download the repository to your local machine.

        git clone https://github.com/jaiswalchitransh/CSP-Map-coloring-using-Backtracking.git
   

3. Open the project in your preferred Python environment (e.g., IDE or terminal).

4. Modify the map, regions, and colors variables in the main block of the map_coloring.py script according to your map and color choices.

5. Run the script (csp_map_coloring.py) and observe the output to see the valid coloring of regions.

Usage

Modify the map, regions, and colors variables in the main block according to your map and color choices.

Run the script:

        python csp_map_coloring.py

Observe the output to see the valid coloring of regions.

Features

• Backtracking Algorithm: Utilizes a backtracking approach to systematically explore and find valid colorings for the map.
• is_valid Function: Checks whether a color assignment for a region is valid based on its neighbors.
• solve_map_coloring Function: Recursively attempts to find a valid coloring for the entire map.
• Main Block: Provides a sample map with regions and their neighbors, along with a list of available colors, demonstrating how the solver works.
