WebPrim’s algorithm is a greedy algorithm that maintains two sets, one represents the vertices included (in MST), and the other represents the vertices not included (in MST). At every step, it finds the minimum weight edge that connects vertices of set 1 to vertices of set 2 and includes the vertex on the other side of edge to set 1(or MST). Web// Prim's Algorithm is a greedy node-based algorithm that finds a MST (minimum spanning tree) in a graph // Description of Algorithm: // 1.
