Abstract

We study the problem of finding a safe and tight lower-bound on the load-balancing objective often found in real-time systems. Our approach involves the formulation of the Multiple Bounded Change-Making Problem which we efficiently solve by using a new symmetry-breaking algorithm. An experimental evaluation shows that the computed lower-bound is optimal in more than 70% of the cases and is able to find more than four times as many decidedly optimal solutions.
