Dijkstra’s algorithm – solving the shortest path of a weighted directed undirected graph

Dijkstra’s Algorithm, also known as Dijkstra’s algorithm, is an algorithm used to solve the shortest path problem of weighted directed graphs or undirected graphs. This algorithm was invented by Dutch computer scientist Edsgel Dijkstra in 1956. It is an algorithm widely used in network routing and other fields. In a 2001 interview, Dr. Dijkstra revealed […]
