WebNov 26, 2024 · Prim's algorithm takes a weighted, undirected, connected graph as input and returns an MST of that graph as output. It works in a greedy manner. In the first step, it selects an arbitrary vertex. Thereafter, each new step adds the nearest vertex to the tree constructed so far until there is no disconnected vertex left.

WebDec 5, 2024 · With Prim's algorithm we find minimum cost spanning tree. The goal is to find minimum cost to cover all nodes. with Dijkstra we find Single Source Shortest Path. The goal is find the shortest path from the source to every other node. Prim’s algorithm works exactly as Dijkstra’s, except. It does not keep track of the distance from the source.
