Web2 (a) The first step of Christofides heuristic is to find the minimum spanning tree on the network. Use Kruskal’s algorithm to identify the MST on the network, and draw your solution on the copy of the network provided. Also, provide a list of the edges that you added to the MST, in the order that you added them. List of edges added: (3,7), (2,5), (1,7), (0,1), …

WebNote that this is an admissible heuristic function. You may consider maintaining a list of visited cities and a list of unvisited cities to facilitate computations. There are several heuristics proposed in literature to estimate distance needed to travel the remaining unvisited cities. We will use the Minimum Spanning Tree heuristic.

In addition, any prespecified … ion television syraceLet G = (V,w) be an instance of the travelling salesman problem. That is, G is a complete graph on the set V of vertices, and the function w assigns a nonnegative real weight to every edge of G. According to the triangle inequality, for every three vertices u, v, and x, it should be the case that w(uv) + w(vx) ≥ w(ux).
