Assume that the shortest distance between nodes a, b, c, and d to node y and the costs from node x to nodes a, b, c, and d are given below:
Day = 5 Dby = 6 Dcy = 4 Ddy = 3 cxa = 2 cxb = 1 cxc = 3 cxd = 1
What is the shortest distance between node x and node y, Dxy, according to the Bellman-Ford equation?
