Dijkstra created it in 20 minutes, now you can learn to code it in the same time. Mark all nodes unvisited and store them. Set the distance to zero for our initial node and to infinity for other nodes. Select the unvisited node with the smallest distance, it's current node now. Before diving into the code, let’s start with a high-level illustration of Dijkstra’s algorithm. First, we initialize the algorithm as follows: 1. We set Reykjavik as the starting node. 2. We set the distances between Reykjavik and all other cities to infinity, except for the distance between Reykjavik and itself, … See more In 1956, Dutch programmerEdsger W.

Web1 Answer. You should use priority queue where the vertex with the shortest distance from the starting vertex will get the highest priority. Initially, all vertices will have the shortest distance of infinity and the starting vertex will have the shortest distance 0. Start by inserting of all vertices (with its edges) from the graph inside the PQ.
