Dijkstra's Algorithm
Dijkstra's Algorithm is a classic graph search algorithm used to find the shortest path between nodes in a weighted graph with non-negative edge weights. It operates by iteratively selecting the node with the smallest known distance from a starting node, updating distances to its neighbors, and marking it as visited. This algorithm is fundamental in computer science for solving pathfinding problems in networks, such as routing in transportation or communication systems.
Developers should learn Dijkstra's Algorithm when working on applications involving network optimization, GPS navigation, or any scenario requiring efficient shortest-path calculations, such as in logistics, game development for AI pathfinding, or network routing protocols. It provides a reliable and optimal solution for graphs with non-negative weights, making it essential for performance-critical systems where minimizing distance or cost is key.
