WebSince costs are integral, this means no cycle has negative cost. By Theorem 2, f is optimal. e-optimality will be our measure of “closeness” to optimality. At a high level, we will divide the itera-tions into phases where f goes from e-optimal to (1 1=n)e-optimal. Effectively, we analyze the algorithm as a cost-scaling algorithm.
