to compute a minimum spanning tree and then drop the k-1 most expensive edges of the. MST. though as there are other approximation algorithms for.
Here we'll look at the greedy paradigm in the context of building minimum spanning trees. 2.2 Minimum Spanning Trees. A tree is an undirected graph which is
The algorithm uses random sampling in combination with a recently discovered linear-time algorithm for verifying a minimum spanning tree. Our computa- tional

Prim's algorithm is a greedy approach to find the minimum spanning tree In this algorithm to form a MST we can start from an arbitrary vertex Algorithm: MST-
Generic approach: A tree is an acyclic graph The idea is to start with an empty graph and try to add edges one at a time always making sure that what is
