WebHowever, early work on predicting lattice reduction [16] has also shown that for small k(say, up to k 25), BKZ sublattices do not follow the Gaussian Heuristic. As a result, while the BKZ 2.0 simulator of [8] makes extensive use of GH(k) for large values of k, it also needs to resort to cumbersome experimental estimations for predicting the result WebPredicting BKZ Z-Shapes on q-ary Lattices.
