Graph traversal is a fundamental concept in computer science, enabling efficient exploration of networks, maps, and various interconnected systems. One of the most renowned algorithms for finding the shortest path between nodes in a graph is Dijkstra’s Algorithm. This algorithm employs a greedy approach, making locally optimal choices at each step with the hope of finding a global optimum.

In this comprehensive guide, we will delve into the workings of Dijkstra’s Algorithm, explore its implementation in Java, and discuss its applications and performance considerations.

Understanding Dijkstra’s Algorithm

Dijkstra’s Algorithm, conceived by Edsger Dijkstra in 1956 and published in 1959, is designed to find the shortest paths between nodes in a graph. It operates on both directed and undirected…
