path-finding-visualization

This project is a simple web-based simulation of a shortest path algorithm using HTML, CSS, and JavaScript. It visually demonstrates how popular algorithms like Dijkstra's or A* find the shortest path from a start node to an end node in a grid-based environment.

Features:

• Interactive Grid: Create your own custom grid by setting width and height to define barriers and obstacles.

• Start and End Nodes: Easily set a start and end node on the grid for the algorithm to find the shortest path between them.

• Algorithm Selection: Choose from various algorithms, such as Dijkstra's, A*, or even Depth-First Search (DFS).

• Visualization: Watch the algorithm in action as it explores the grid and marks the shortest path after execution.

Getting Started:

1. Clone this repository to your local machine or download the ZIP file.

2. Open the index.html file in your web browser.

3. Define the start and end nodes on the grid, add barriers, and select the algorithm of your choice.

   • Double Click a box on grid to select start node.
   • Ctrl + Double Click a box on grid to select end node.

4. Add weight nodes on the grid (optional).

   • Click a box on grid to set it as weighted node with weight Infinity.
   • Ctrl + Click a box on a grid to set it as weighted node with weight of 5.

5. Click the "Start" button to watch the algorithm find the shortest path.

Hosting on a Web Server

1. Choose a Linux Distribution:

   • Select a Linux distribution for your web server. Common choices include Ubuntu, CentOS, or Debian.

2. Install a Web Server:

   • For Ubuntu/Debian:

     • Update the package list: sudo apt update
     • Install Apache web server: sudo apt install apache2

   • For CentOS:

     • Update the package list: sudo yum update
     • Install Apache web server: sudo yum install httpd

3. Copy Relevant Files:

   • Place your website files in the appropriate directory. For Apache, it's usually located in /var/www/html/. You can use SCP, FTP, or other methods to transfer your files to the server.

   • sudo cp <path-to-directory>/path-finding-visualizer/* /var/www/html

4. Configure Firewall (if necessary):

   • Open the web server's port (usually port 80) in your firewall to allow incoming HTTP traffic. For example, on Ubuntu, you can use:

     sudo ufw allow 80/tcp

5. Start the Web Server Service:

   • For Ubuntu/Debian:

     • Enable Apache to start at boot: sudo systemctl enable apache2
     • Start Apache: sudo systemctl start apache2

   • For CentOS:

     • Enable Apache to start at boot: sudo systemctl enable httpd
     • Start Apache: sudo systemctl start httpd

6. Access Your Website:

   • Open a web browser and enter your server's IP address or domain name. You should see your website.

7. Optional: Domain Configuration:

   • If you have a domain name, you can configure your DNS settings to point to your server's IP address.

Customization:

Feel free to modify the CSS and JavaScript to further customize the appearance and behavior of the simulation to suit your needs.
