Applications: In electronic circuit design to minimize the wire length. This website uses cookies to improve your experience. In this case, as well, we have n-1 edges when number of nodes in graph are n. In Kruskal's Algorithm, we add an edge to grow the spanning tree and in Prim's, we add a vertex. C Program To Implement Prim’s Algorithm to Find Minimum Spanning Tree This algorithm is directly based on the generic MST (Minimum Spanning Tree) algorithm. In this case, we have two edges weighing 2, so we can choose either of them (it doesn't matter which one). It works in a greedy manner. In this article, we will implement Prim’s algorithm to find MST. Every vertex is associated with a length and predecessor. Additionally Edsger Dijkstra published this algorithm in 1959. We can draft a pseudocode of the above algorithm as follows − This algorithm is directly based on the MST (minimum spanning tree) property. again and again add edges to tree and tree is extended to create Initially all the vertices are temporary and at every step, a temporary vertex is made permanent vertex.
