central limit theorem convergence acceleration for DGS efficiency

[Marcio Barbado, Jr.]

Hi. This is to share some results of my MSc work, still in progress,
which is about discrete Gaussian sampling for RLWE-based cryptography
[1]. The referred work samples in a slightly different fashion.
Comparisons are made against the CDT sampling strategy, and the
results lead us to believe that the adopted strategy offers consistent
efficiency gains for a number of contexts, mostly regarding digital
signatures.
