WebJan 1, 2015 · A greedy algorithm also has to make choices, and does so on the basis of local optimizations that may not be optimal globally. But it is expected to succeed anyway and does not have to backtrack: the price of greediness is that the "cost" (however defined) of the result obtained by the algorithm may be higher than the cost of the optimal solution.

WebPrim's algorithm to find minimum cost spanning tree (as Kruskal's algorithm) uses the greedy approach. Prim's algorithm shares a similarity with the shortest path first algorithms. Prim's algorithm, in contrast with Kruskal's algorithm, treats the nodes as a single tree and keeps on adding new nodes to the spanning tree from the given graph.
