Using the same approach as for Algorithm 4 and Algorithm 5, we implemented a uSVP simulator for BKZ, described in Algorithm 6. In this case, the basis profile after a number of tours of BKZ-\(\beta \) is simulated in one shot using the simulator. Given that the block size is fixed, the probabilities are only accumulated over tours.
