dijkstra's algorithm example step by step ppt
What are the problems with Dijkstra's algorithm?
The Dijkstra Shortest Path algorithm computes the shortest path between nodes.
The algorithm supports weighted graphs with positive relationship weights.
The Dijkstra Single-Source algorithm computes the shortest paths between a source node and all nodes reachable from that node.What is Dijkstra's algorithm with suitable examples?
One of the problems with using Dijkstra's algorithm on the Internet is that you must have a complete representation of the graph in order for the algorithm to run.
The implication of this is that every router has a complete map of all the routers in the Internet.
