Prims complexity
In computer science, Prim's algorithm (also known as Jarník's algorithm) is a greedy algorithm that finds a minimum spanning tree for a 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 operates by building this tree one vertex at a time, from an arbitrary starting vertex, at each step adding the cheapest possible connection from the tree to another ve… WebNov 25, 2024 · Dijkstra’s algorithm finds the shortest path, but Prim’s algorithm finds the MST. Dijkstra’s algorithm can work on both directed and undirected graphs, but Prim’s …
