Dijkstra's Algorithm Explained
In computer science, Dijkstra's algorithm is a fundamental pathfinding and graph traversal algorithm created by the Dutch computer scientist Edsger W. Dijkstra in 1956. This powerful algorithm finds the shortest path between nodes in a graph, which is essential in applications like network routing, mapping systems, and in solving various optimization problems.
How It Works
The algorithm maintains a set of nodes whose shortest distance from the source is known and continuously expands this set by adding the node with the smallest tentative distance until the destination node's shortest distance is finalized.
- Pick the vertex with the smallest tentative distance.
- Update its neighbors' distances.
- Repeat until all nodes are processed.
Key Concepts
Dijkstra's algorithm is known for its efficiency and ease of implementation, particularly given its non-negative edge weights constraint, common in many real-world scenarios.

At Froge, we love Dijkstra's algorithm because it helps us hop from lily pad to lily pad on the shortest path possible. Efficiency is key when exploring the pond! 🐸
