Here is an algorithm described by the Dutch computer scientist Edsger W. Dijkstra in 1959. Let's create an array d [] where for each vertex v we store the current length of the shortest path from s to v in d [ v] . Initially d [ s] = 0 , and for all other vertices this length equals infinity.

Webdijkstra. C++ implementation of Dijkstra's shortest path algorithm. Running time: O (E log (V)) Implementation doesn't requere adding all nodes to priority queue in the begining of algorithm. So it can be used for really big graphs, and to find the shortest path from a single source to the closest of a set of target nodes on infinite graphs. WebJul 21, 2014 · Dijkstra’s Algorithm in C.
