Approximate solution for Travelling Salesman Problem using MST

WebExpert Answer. (a) An upper bound of the TSP can be obtained by finding a minimum spanning tree (MST) of the given distance matrix. Applying Kruskal's algorithm, we obtain the following MST: 1--4--5--3--2--6 The total distance of this MST is:21 + 19 + 13 + 31 + 27 = 111 Therefore, an upper bound of the TSP is 111.

"Webmind, we will focus on the TSP instance on G. 2.1 Approximation using MST For the rest of this note, we will refer to metric TSP as simply \TSP" for convenience. First, we will use the MST of the metric completion to construct an approximate tour. Obviously, the optimal value for a tour is at least the value of the minimum spanning tree, since " - Tsp using mst

WebTime Complexity: The running time for prim’s algorithm is O(VlogV + ElogV) which is equal to O(ElogV) because every insertion of a node in the solution takes logarithmic time. Here, E is the number of edges and V is the number of vertices/nodes. However, we can improve the running time complexity to O(E + logV) of prim’s algorithm using Fibonacci Heaps.
