How To Implement the A* Search Algorithm By Solving the Shortest Path Through a 2D

Generating and solving random mazes: A step-by-step guide with A* algorithm in JavaScript

JavaScript Challenges: Beginner to Master — Task #54

Create a function that generates a random maze and finds the shortest path from the start to the end using a search algorithm.

Challenge in Detail

Create a function that generates a random maze and finds the shortest path from the start to the end using a search algorithm. The function should take the dimensions of the maze as input and return a 2D array representing the maze with the shortest path marked. Implement a search algorithm like A* or Dijkstra’s to find the shortest path.

Why Maze Solving? — More Than Just a Puzzle

Historical and Cultural Significance

From ancient labyrinths to modern-day escape rooms, mazes have been part of human culture for thousands of years. We must translate this challenge to computers to create algorithms that mimic and surpass human problem-solving.

Fundamental to Algorithm Study

You can learn graph theory and search algorithms using the maze runner problem. Each cell in a maze is a node, and adjacent cells are edges. Solving a maze is essentially a graph traversal problem, so it’s a big part of algorithm courses.

Broad Applicability

The algorithms used to solve mazes, such as Depth-First Search (DFS), Breadth-First Search (BFS), A*, and Dijkstra’s algorithm, apply to many problems beyond mazes. For example, they can be used in:

• Routing and navigation systems.
• Network data packet forwarding.
• Artificial Intelligence pathfinding, such as in video games.

Benchmarking and Optimization

Maze generation and solving provide a tangible way to compare the efficiency of different algorithms. For instance, while BFS might guarantee the…
