What is the difference between Dijkstra and Prim's algorithm?

• Answer:

  Dijkstra's algorithm is almost identical to that of Prim's. The algorithm begins at a specific vertex and extends outward within the graph, until all vertices have been reached. The only distinction is that Prim's algorithm stores a minimum cost edge whereas Dijkstra's algorithm stores the total cost from a source vertex to the current vertex. More simply, Dijkstra's algorithm stores a summation of minimum cost edges whereas Prim's algorithm stores at most one minimum cost edge.
