Prim algorithm for minimum spanning tree
WebJan 9, 2010 · The priority of each vertex is the cost of connecting the vertex with the current spanning tree - this is the minimum weight of all edges connecting the vertex with the current tree or infinity if there ... Finding a Minimum Spanning Tree from an Adjacency List where the Adjacency List is in a string array using Prims Algorithm ... 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…
