Prim's AlgorithmPrim's Algorithm is used to find the minimum spanning tree from a graph. Prim's algorithm finds the subset of edges that includes every vertex of the graph such that the sum of the weights of the edges can be minimized. Prim's algorithm starts with the single node and explore all the adjacent nodes with all the connecting edges at every step. The edges with the minimal weights causing no cycles in the graph got selected. The algorithm is given as follows. Algorithm
Example :Construct a minimum spanning tree of the graph given in the following figure by using prim's algorithm. Solution
The graph produces in the step 4 is the minimum spanning tree of the graph shown in the above figure. The cost of MST will be calculated as; cost(MST) = 4 + 2 + 1 + 3 = 10 units. C Program:Output 0 1 5 0 2 0 0 3 8 1 4 6
