Before revision:  Thus, we are able to achieve a reduction in complexity (from O(n^{2.5} \log n) of the hybrid policies to O(n^2 ) ) with a minimal drop in the delay performance.
After revision:  Thus, we are able to achieve a reduction in complexity (from O(n^{2.5} \log n) of the hybrid policies to 2n^2 + 2n ) with a minimal drop in the delay performance.
