The … 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.

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.
