WebMar 17, 2024 · The sequence of steps for Prim’s Algorithm is as follows: Choose a random vertex as starting vertex and initialize a minimum spanning tree. Find the edges that connect to other vertices. Find the edge with minimum weight and add it to the spanning tree. Repeat step 2 until the spanning tree is obtained. WebIn computer science, Prim's (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 ... scruffing in cats
