Open loop … 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. sick eating
