In computer science, Prim’s algorithm is a greedy algorithm that finds a minimum spanning tree for a connected weighted undirected graph. This means it finds a subset of the edges that forms a tree that includes every vertex, where the total weight of all the edges in the tree is minimized. The algorithm was developed in 1930 by Czech mathematician Vojtěch Jarník and later independently by computer scientist Robert C. Prim in 1957 and rediscovered by Edsger Dijkstra in 1959. Therefore it is also sometimes called the DJP algorithm, the Jarník algorithm, or the Prim-Jarník algorithm. Other algorithms for this problem include Kruskal’s algorithm and Borůvka’s algorithm. These algorithms find the minimum spanning forest in a possibly disconnected graph. By running Prim’s algorithm for each connected component of the graph, it can also be used to find the minimum spanning forest.
