A Comparative Analysis of BFS, DFS, Dijkstra’s, and A* Algorithms Using a Practical Maze Solver Implementation
Exploring graph traversal and pathfinding algorithms is fundamental for developers working on navigation, game development, and AI applications. In a recent project, I delved into four prominent algorithms—Breadth-First Search (BFS), Depth-First Search (DFS), Dijkstra’s algorithm, and A* search—by creating an interactive maze solver demo in TypeScript. This approach not only reinforces theoretical understanding but also provides practical insights into their behavior across varied scenarios.
Objective of the Study
Rather than relying solely on abstract explanations, I aimed to observe each algorithm’s performance and decision-making process through real-time visualization. By designing a maze solver application, I was able to compare how these algorithms explore the problem space, handle obstacles, and find optimal paths.
Implementation Details
The maze solver was built using TypeScript, a popular choice for building scalable and maintainable web applications. The demo allows users to generate or load different maze configurations and visualize the step-by-step execution of each algorithm. This hands-on approach helps in understanding their operational nuances and efficiency in different circumstances.
Practical Insights and Applications
This exploration is particularly useful for students preparing for technical interviews, educators designing curriculum, or developers seeking to optimize pathfinding logic in their projects. Visualizing algorithms in action demystifies complex concepts and provides a clearer understanding of their strengths and limitations.

Invitation for Feedback and Discussion
Have you experimented with these algorithms in your own projects? Do you employ alternative strategies for pathfinding? I welcome your insights, experiences, and suggestions. Engaging with the community helps us improve our understanding and application of these powerful algorithms.
Conclusion
By combining theoretical knowledge with practical implementation, we gain a more intuitive understanding of fundamental algorithms like BFS, DFS, Dijkstra’s, and A*. Visual tools and demos serve as valuable resources for educators, students, and developers aiming to deepen their grasp of pathfinding techniques in real-world scenarios.
