A* Pathfinding Algorithm Explained

Web Reference: A* is an informed search algorithm, or a best-first search, meaning that it is formulated in terms of weighted graphs: starting from a specific starting node of a graph, it aims to find a path to the given goal node having the smallest cost (least distance travelled, shortest time, etc.). Jul 23, 2025 · Informally speaking, A* Search algorithms, unlike other traversal techniques, it has “brains”. What it means is that it is really a smart algorithm which separates it from the other conventional algorithms. Interactive tutorial for A*, Dijkstra's Algorithm, and other pathfinding algorithms

YouTube Excerpt: Hey guys! Welcome back to another programming video! Today, I show how the best pathfinding algorithm works, the a* algorithm. It is quite simple but really powerful and efficient. It beats many other pathfinding algorithms in terms of time and efficiency to arrive at the destination with the shortest path. In this video, I only take a look at explaining the algorithm. Check out my second video of this series where I show how to code this in javascript! Thanks for watching and see you in the next video! :) A* Algorithm Wikipedia : https://en.wikipedia.org/wiki/A*_search_algorithm Code For This Series (Github) : https://github.com/HritikRC/A-Pathfinding-Algorithm/ Playlist For This Series : https://youtube.com/playlist?list=PLEtXCX1lakbgvh01C6HapSbCv2sbQwyK1 Background Music : Smooth Sailing (with Guitar) by Audionautix is licensed under a Creative Commons Attribution 4.0 license. https://creativecommons.org/licenses/by/4.0/ Artist: http://audionautix.com/
