Show that the Bellman-Ford algorithm, when run on the constraint graph for a system Ax b

Question:

Show that the Bellman-Ford algorithm, when run on the constraint graph for a system Ax ≤ b of difference constraints, minimizes the quantity (max {xi} – min {xi}) subject to Ax ≤ b. Explain how this fact might come in handy if the algorithm is used to schedule construction jobs.
