Dijkstra vs. A Star on Real Map | Europe To Asia

Dijkstra’s Algorithm and the A* (A Star) Algorithm are both search algorithms, but they differ in how they explore the search space. In this video, on real map you can find how both path finding algorithms works.

In short:

👉 Dijkstra’s Algorithm: Finds the shortest path by exploring all possible directions outward from the start node, always choosing the path with the lowest cumulative cost so far. It guarantees the shortest path but can be slower, especially in large graphs, because it doesn’t consider the destination until it’s reached.

👉 A Star Algorithm: Improves on Dijkstra by adding a heuristic function that estimates the remaining distance to the goal. This allows A* to prioritize paths that seem more promising, usually exploring fewer nodes and reaching the target faster. If the heuristic is admissible (never overestimates), A* also guarantees the shortest path.
