Lecture 7: Minimum Spanning Trees and Prim’s Algorithm

Minimum Spanning Tree Problem MST Problem: Given a connected weighted undi-rected graph , design an algorithm that outputs a minimum spanning tree (MST) of . Question: What is most intuitive way to solve? Generic approach: A tree is an acyclic graph. The idea is to start with an empty graph and try to add

First, we create a minimum spanning tree the weight of which is a lower bound on the cost of an optimal traveling salesman tour. Using this minimum spanning tree we will create a tour the cost of which is at most 2 times the weight of the spanning tree. We present the algorithm that performs these computations using the MST-Prim algorithm.

light edge crossing some cut. But the triangle is cyclic, so it is not a minimum spanning tree. Problem 23.1-10 Given a graph Gand a minimum spanning tree T, suppose that we decrease the weight of one of the edges in T. Show that T is still a minimum spanning tree for G. More formally, let T be a minimum spanning tree for Gwith edge

About this Tutorial

If we have an algorithm for a specific problem, then we can implement it in any programming language, meaning that the algorithm is independent from any programming languages. Algorithm Design The important aspects of algorithm design include creating an efficient algorithm to solve a problem in an efficient way using minimum time and space.
