WebDijkstra's algorithm was, originally, published by Edsger Wybe Dijkstra, winner of the 1972 A. M. Turing Award. Explanation: Step 1: Set the distance to the source to 0 and the distance to the remaining vertices to infinity. Step 2: Set the current vertex to the source. Step 3: Flag the current vertex as visited. WebBelow is a pseudocode algorithm that you may use in your implementation.
