N-Queen Algorithm Visualizer

Welcome to the N-Queen Algorithm Visualizer! This project is a web application that allows you to visualize the N-Queen problem using HTML, CSS, and JavaScript. The N-Queen problem is a classic puzzle where you need to place N queens on an N×N chessboard in such a way that no two queens attack each other. The goal of this visualizer is to demonstrate how the algorithm solves the N-Queen problem step by step.

Introduction

The N-Queen Algorithm Visualizer is an educational tool that helps users understand how the N-Queen problem can be solved using a backtracking algorithm. The project provides an interactive chessboard interface where users can select the board size (N) and watch the algorithm in action, placing queens one by one until a valid solution is found. The visualization will show the backtracking process, highlighting the placement and removal of queens.

Features

• Interactive chessboard where users can select the board size (N).
• Visualization of the backtracking algorithm to solve the N-Queen problem.
• Animation and highlights for each step of the algorithm for better understanding.
• Display of the final solution if a valid arrangement of queens is found.

Technologies Used

The N-Queen Algorithm Visualizer is built using the following technologies:

• HTML5, CSS3, and JavaScript for the frontend development.
• SVG (Scalable Vector Graphics) for rendering the chessboard and queens.
• Your Preferred JavaScript Library (Optional - if using any specific JavaScript library).

Setup

1. Clone the repository from GitHub.
2. Open the index.html file in your web browser.
3. Choose the board size (N) for the N-Queen problem using the provided input or dropdown.
4. Click on the "Visualize" button to start the visualization.

Usage

1. Once the visualization starts, the application will attempt to solve the N-Queen problem using the backtracking algorithm.
2. Watch as queens are placed on the chessboard one by one, attempting to find a valid solution.
3. Observe how the algorithm backtracks when it encounters conflicts and tries different arrangements until a solution is found or all possibilities are exhausted.
4. If a valid solution is found, the visualization will display the final arrangement of queens on the chessboard.

Algorithm Explanation

The N-Queen problem is solved using a backtracking algorithm, which is a type of depth-first search. At each step, the algorithm attempts to place a queen on the board, and if a conflict is detected, it backtracks to the previous state and tries a different position. The process continues until a valid arrangement of queens is found or all possibilities are exhausted. The visualization will highlight each step, making it easier to understand the backtracking process.
