However, opening the neighboring facilities i -- 1 , . . , d are not independent events: for instance, if two of these neighbors are in the same cluster, then only one of them can be opened. The next question is: can the conditioning between these events be harmful? Fortunately, the answer is no, and it is fairly intuitive to see why this is the case. If it happens t h a t none of the first k neighbors of j have not been opened, this only makes it more likely t h a t the next cheapest facility is, in fact, open.

In phase r we might add by rounding extra e,. Since ~-']~,,<, e,, < er we conclude that the weights of the small jobs of a state vector in the first layer of a phase exceeds the total rounded weight of the small jobs available by at most 26, and thus qe, < W1 -t- 2er. The lemma holds for nodes inside phases too, since each time we reduce q, by some number qx, W1 is reduced by at most (ql - 2)e. This completes the proof of the lemma. In a cover vector the small jobs coordinate q' is bounded above by the small jobs coordinate of the node for which this edge is outgoing.
