1. A method for determining a rebalanced configuration of buses, racks, and components associated with a given power distribution unit, the rebalanced configuration identifying a number of components that should be assigned to a given phase for one or more racks associated with the given power distribution unit, the method comprising:
defining variables for each rack and phase;
preserving, with one or more processors, a number of components per rack;
limiting, with one or more processors, per-rack phase imbalance;
minimizing imbalance among phases; and
minimizing a number of component moves.
