(a) For the network shown in Figure 5.42, solve the vertex 3-center problem. Clearly indicate where you should locate the three facilities.

(b) What is the objective function value for the vertex 3-center problem?

(a) For the network shown in Figure 5.43, solve the vertex 3-center problem. Clearly show the lower and upper bounds that you obtain on each iteration of the algorithm.

(b) What is the objective function for the vertex 3-center problem?

(c) What are the locations of the three nodes that solve the vertex 3-center problem on this network?
