Dijkstra’s Algorithm for Adjacency List Representation – Greedy Algorithm – We have discussed Dijkstra’s algorithm and its implementation for adjacency.In this post, O(ELogV) algorithm for adjacency list representation is discussed.
Dijkstra’s shortest path algorithm – Greedy algorithm – Dijkstra’s algorithm is very similar to Prim’s algorithm for minimum spanning tree. Like Prim’s MST, we generate a SPT (shortest path tree) with given source as root.
Prim’s MST for Adjacency List Representation – Greedy algorithm – We have discussed Prim’s algorithm and implementation for adjacency matrix representation. The time complexity for the matrix representation is O(V^2).
