Graphs in Java: Minimum Spanning Trees - Prim

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… WebExecuting Prim’s algorithm involves the following steps: Set up the minimum spanning tree using a randomly chosen vertex.
