Question: Suppose that every row in the matrix A of a linear program Ax b corresponds to a difference constraint, a single-variable constraint of the form

Suppose that every row in the matrix A of a linear program Ax ≤ b corresponds to a difference constraint, a single-variable constraint of the form xi ≤ bk, or a single-variable constraint of the form -xi ≤ bk. Show how to adapt the Bellman-Ford algorithm to solve this variety of constraint system.
